Chapter 11: November

By November the short daylength limited how much birding I could do before and after work, and my number of outings decreased substantially relative to the preceding two months. I continued checking the White Rock waterfront as I was still missing several alcid species and was expecting the appearance of Ancient Murrelets any day.  

Ancient Murrelet is a fairly recent addition to the SemiPen bird list, with the first record at the White Rock pier dating back only to October 2017. This seems hard to believe considering the White Rock pier now has a reputation as one of the most reliable locations to see Ancient Murrelets in Metro Vancouver. They have been seen almost every year since and sometimes by the dozens. I believe this is a fairly recent phenomenon since the White Rock pier has received coverage from birders for decades and surely such a passage of Ancient Murrelets would not have gone undetected. 

On November 6, I spotted a distant murrelet while scoping from Kwomais Point. White scapulars on uniformly dark upperparts identified this one as a Marbled Murrelet, which in recent years has become the harder of the two murrelet species to find on the SemiPen so I was pleased. On the 8th there were three female Redheads at the White Rock Pier. The first report of Ancient Murrelets from the White Rock pier came on the 24^th, and I caught up to them on the 29^th; three separate groups totalling fifteen individuals. However, I still could not find a Common Murre.

Over at Blackie Spit, small flocks of Black-bellied Plovers from Boundary Bay continued gathering on the pilings at high tide, each time bringing something different. On the 5^th I found two Red Knots with this flock and on the 16^th a late Short-billed Dowitcher. Both species continued to be seen sporadically throughout the month. The now resident Willet would often roost with this group, sometimes joined by the second Willet from Boundary Bay. A lingering Lesser Yellowlegs also continued throughout the month.

Chapter 10: October

Blackie Spit remained the focus of my birding in October. My targets consisted of a mix of regular late fall migrants such as Northern Shrike, possible but unlikely October rarities such as Tropical Kingbird, and unprecedented mega rarities such as Tundra Bean-Goose. 

Cackling Geese continued to gather in Mud Bay in good numbers throughout the month, peaking at an estimated 3,600 on the 13^th, and joined by hundreds of Snow Geese later in the month. Despite the promise that these flocks contained, the only other species I could pick out was Greater White-fronted Goose; eighteen on the 10^th and four on the 13^th.  The nearest Tundra Bean-Goose bypassed the Semiahmoo Peninsula 650 km to the east.

On the 3^rd another Horned Lark was present at Blackie Spit, about two weeks after the last report in September. On the 5^th, a late Osprey was a year bird and one that I had accepted missing since I only have a handful of October records from anywhere in Metro Vancouver. A trickle of late migrants continued into early October, with a Black-throated Gray Warbler on the 5^th, a Hammond’s Flycatcher and a Yellow Warbler on the 10^th, and best of all a Nashville Warbler on the 11^th.  On the 16^th, a Mountain Bluebird was found at Blackie Spit, but I could not make it out there that same day. While searching unsuccessfully the next day, I found a Swamp Sparrow in the reed canary grass by the base of the spit. This was just the second record for the SemiPen and at the exact same location and time of year as the first record, almost a decade ago. A second year bird that same day was a juvenile American Golden-Plover, which I saw again on the 22^nd along with my second American Kestrel of the year.  Blackie Spit is typically not a hotspot for owls, but on the 24^th and 25^th I managed to see three species in two days there: Barred, Great Horned, and Short-eared Owls. Lapland Longspurs were also a reliable feature of Blackie Spit throughout the second half of October, including a high count of eight on the 25^th. Much to my relief, a Black-crowned Night-Heron, which I had missed earlier in the year, returned to Nicomekl Portage Park on the 29^th.

Throughout October I started visiting to the White Rock waterfront more frequently as there was a small handful of target birds that are most reliable there. Several thousand Western Grebes gather in Semiahmoo Bay from late September to mid-November, and among these flotillas there are sometimes Clark’s Grebes. In addition to the inherent challenge with this needle in a haystack scenario, the grebes spend a lot of time sleeping or well offshore which further diminishes the odds of finding the one in one thousand Clark’s Grebe that may be present. Indeed, these were the challenges that I encountered throughout October and during each visit I felt like I had adequately seen only a small fraction of the grebes present. On the 13th I attempted to kayak out to the distant grebes, which was also not without its challenges. Although the sea state started out calm, a slight chop gradually developed. Given the low vantage point when seated in a kayak, even a slight chop hides grebes remarkably well in its troughs. More frustratingly, it also rotated my kayak in undesired directions whenever I stopped paddling to scan the grebes. I picked out one Clark’s x Western Grebe hybrid but the real measure of success was returning to land without having submerged my optics.

Several days later, on the morning of the 21^st, ROFO texted to notify me that many grebes were feeding relatively close off the end of the White Rock pier and showing well. Seizing the opportunity, I headed to the pier and an hour later picked out at a Clark’s Grebe! A female Redhead, found by ROFO was mingling with scaup west of the pier. The day before I had a male east of the pier. This was another of my target birds.

Chapter 9: September

September is the peak of southbound migration in Vancouver and there were still lots of reasonably easy targets, at least at the Metro Vancouver scale, that I still needed for my SemiPen year list. Blackie Spit seemed like the place with the best potential for most of these, as well as anything unexpected, so I focused my birding there for most of the month, visiting it twenty times. 

Things started off hot with a Lark Sparrow found by CVWE on the 2^nd, which was seen by many including me. There were now two Stilt Sandpipers at Blackie Spit on the 2^nd and 3^rd. On the morning of the 10^th, there was a Red-necked Phalarope and two Baird’s Sandpipers, just my second sighting of each this year. However, the real highlight was a Palm Warbler present briefly in the northeast corner of the Saveneye area before launching itself northeast over the Nicomekl estuary. There was a good morning flight of warblers that day, all of which passed through the Saveneye area in quick succession and onward to the northeast (in the opposite direction of the prevailing southbound migration). Migration was so good that morning that I returned in the evening to see if anything else had touched down and stayed. I found a Horned Lark on the spit and a couple Chipping Sparrows near the entrance to the Saveneye area. The lark stayed for several days and was eventually joined by a second bird.

By mid-September variable sized Black-bellied Plover flocks started coming over from Boundary Bay during very high tides. On the 14^th there was a golden plover with them, but I only saw it in flight so could not identify it to species. That same flock contained a couple Sanderling, which were an overdue year bird. On the 16^th the plover flock brought with it two Red Knots but no golden plovers. On the 17^th there was a Mourning Dove, just my second for the year, and another on the 29^th. I also saw my first Lapland Longspur of the year on the 17^th, then again on the 18^th, 20^th, and 21^st. Also On the 20^th the Willet appeared for the first time this fall and a Common Nighthawk flew over at dusk. The next day I finally saw a Vaux’s Swift and the day after a flock of twenty; just as I was beginning to worry about missing this species. Another Red-necked Phalarope and my first Pectoral Sandpipers of the year, a flock of ten, were also present on the 22^nd. But the best bird that day was an American Redstart, again, in the Saveneye area and another SemiPen first for me. A week later three California Scrub-Jays, along with many Steller’s Jays, were flying back and forth between Blackie Spit and the Crescent Beach neighbourhood on the 27^th. A flock of five Pectoral Sandpipers that day were just my second and last sighting of that species this year.

On the 29^th, I finally saw a Sharp-shinned Hawk, which was my 200^th year bird. I was starting to worry about this one too, since mid to late September represents their peak migration on the north shore mountains, where it is not unusual to see upwards of twenty in a single day. Such raptor migration does not occur on the Semiahmoo Peninsula, so encounters with Sharpies are chance events, unless one is stalking your bird feeder.  Large numbers of Cackling Geese started to gather in Mud Bay, usually loafing on the mudflats at dawn than flying northeast to the fields within a couple hours of sunrise. They numbered in the hundreds by the middle of the month and in the thousands by its end. On the 29^th, I picked out two Greater White-fronted Geese from this flock in flight while at Elgin Heritage Park. I saw my first White-throated Sparrow of the year there that day as well.

A frustrating miss in September was an ibis, which was seen flying over the spit by PHWR and DEHL on the 19^th. Perhaps that was for the best since temptation to count it as White-faced Ibis would have been very great. If one is strict, most juvenile ibises cannot be identified to species in flight, or perched for that matter, although the odds here are heavily weighted (like 99.9%) towards White-faced Ibis.

Chapter 8: August

By early August, the southbound shorebird migration is in full swing and there were still many species that I needed for my SemiPen year list. However, it seemed that the shorebird flocks were not visiting Blackie Spit much, other than yellowlegs which were often present in impressive numbers. I saw only small numbers of peeps and the plover flocks seemed to roost on the living dykes – the new flood protection structures – at Boundary Bay instead of gathering on the saltmarsh across from Blackie Spit. While birding at Boundary Bay, it was not unusual for me to see two or three shorebird species that I still needed for my SemiPen year list with the Semiahmoo Peninsula in the background. 

On August 10, I was pleased to find a Stilt Sandpiper with the yellowlegs at Blackie Spit.  The next day, I finally connected with a single Semipalmated Sandpiper there. On August 14 and 15, I noticed a sudden influx of Baird’s Sandpipers at Boundary Bay, so figured now was the time to try for one at Blackie Spit. In my experience they are most reliable on the actual spit during very high tides, which flood the remainder of Mud Bay. On such a tide on August 16, I observed two Baird’s Sandpipers at the end of the spit. As a bonus, there were also four Red-necked Phalaropes and a juvenile Franklin’s Gull visible from the end of the spit.  The latter was the same bird I found at Boundary Bay the day before and I saw it again on August 19, this time among a gull roost at Crescent Beach.

Elgin Heritage Park has good potential for three key SemiPen target birds in August. The first, Green Heron, I was lucky to observe on my first visit there on August 4. Solitary Sandpiper quickly followed on August 7.  Both birds stayed for over a week and I saw them repeatedly. My third key target was Northern Waterthrush. One has never been seen there, at least according to eBird, but there is a predictable passage of waterthrushes through Metro Vancouver in the second half of August and the habitat at Elgin Heritage Park seems perfect. Despite eight visits to Elgin Heritage Park throughout the month, and another two to Crescent Park which is where I have seen my one and only waterthrush on the SemiPen, I never connected with one. In fact, the fall of 2024 turned out to be very poor for Northern Waterthrushes throughout Metro Vancouver, with much fewer reports than in previous years.

A much more common bird that I still needed, and one that time was running out for, was Cliff Swallow. Except for Barn Swallows, the other swallow species tend to disappear from Metro Vancouver early and inconspicuously. I was beginning to see large numbers of Barn Swallows feeding over the saltmarsh across from Blackie Spit, and with a scope could occasionally pick out all the other species except for Cliff. I suspected that most of these Barn Swallows roosted in the corn fields along 40^th Avenue and an evening visit to Elgin Heritage Park confirmed this when I saw several hundred swarming above and descending into the corn stalks across the river for the night. I was surprised to see a Short-eared Owl fly over, but still could not pick out a Cliff. Finally, on August 11, I again observed several hundred Barn Swallows wheeling above the same corn fields while scoping from Elgin Heritage Park. However, on this day, they frequently landed on the dirt bank of the newly raised dyke on the north side on the Nicomekl River. This allowed efficient scope views and I was able to pick out a single Cliff Swallow; a sooty brown and poorly patterned fresh juvenile that barely resembled a Cliff Swallow save for its buffy rump. This flock also contained many Bank Swallows. I counted nine perched on a single scan and there were surely more among the swallows that were airborne. I ended up seeing Cliff Swallows again on August 21, this time at Blackie Spit when many swallows were landing at the end of the spit on a blustery morning.

Other notable odds and ends from August included a Bullock’s Oriole at Blackie Spit on the 10^th, a Chipping Sparrow at Blackie Spit on the 11^th, and a Great Horned Owl at Alderwood Park on the 14^th.

Chapter 7: July

As expected, birding quieted down in July. There was not a lot of potential year birds to search for and I only turned up two: a juvenile Mourning Dove at Blackie Spit on July 13 and the first southbound Lesser Yellowlegs on July 22. 

Mourning Dove at Blackie Spit

Perhaps more notable was the absence of some birds. Mourning Dove, which were once reliable at Elgin Heritage Park throughout the summer months, were seemingly absent this year. As were Marsh Wrens; turns out I was very lucky to find one at Blackie Spit on March 17. The marsh at Elgin has previously hosted Virginia Rails during most summers, but there were no reports this year. My only sighting of a Virginia Rail on the SemiPen this year turned out to be a vocal bird on April 18 in the ephemeral wetland that has formed on the old Riverside Golf Course. On the other hand, the Sora that was first reported at Elgin Heritage Park in late April remained until at least early July. There were a couple eBird reports of two Soras at Elgin, so perhaps they nested, though I’m not aware of any sightings of chicks. 

Chapter 6: June

The little woodlot next to the parking lot at Blackie Spit always struck me like it should be a migrant trap. The tall black cottonwoods, fringed by red alder and birch, create an island of habitat that is unlike its surroundings. I’ve often imagined some eastern warbler overshoot setting up a territory there – perhaps a Chestnut-sided Warbler as often happens in Metro Vancouver. But that had never happened, at least not until June 7^th of this year. 

As I entered the woodlot that morning, a rising buzzy trill in the background of the dawn chorus caught my attention. “Huh, that sounds like a Northern Parula” I thought. I managed a faint recording before it went quiet. I wandered about the woodlot back and forth but there was no further sign of the bird. There was a good push of late migrants with several other warbler species on the move as well as a singing Red-eyed Vireo, a SemiPen first for me. Then, exiting the woodlot on the east side, I could hear the suspected parula singing from the oaks at the corner of Dunsmuir and Gilley St., less than fifty meters from where the Oriental Turtle-Dove was first found. This time the bird was right in front of me, but again I failed to see it, and again after a few minutes it went quiet. But it had also switched its song type to another Northern Parula song type. At this point I was sure it was one, but still had not seen it. A Bullock’s Oriole distracted me briefly as it flew over chattering; another good SemiPen bird. After some fifteen minutes of silence, which felt like an eternity, I returned to the woodlot and to my relief, again heard the suspected parula singing from the birches near where I first heard it. This time I managed some brief glimpses, enough to confirm the identification, and put the word out. A handful of birders managed to see it that morning before it sang for the last time around 11 am. Remarkably this was not the first parula for the SemiPen; CAGI had found one at near-by Elgin Heritage Park on May 30, 2007.

Throughout the remainder of June, I was pleased with multiple sightings of Black Swifts and Common Nighthawksover the SemiPen, the latter over my yard on a couple occasions. On the morning of June 25, I scoped from Kowmais Point. The water was glassy and the sun directly behind me, perfect conditions for picking out distant alcids on the water. I counted nineteen Rhinoceros Auklets, which are fairly reliable here in summer under the right conditions. I was more lucky to intercept two flying Pigeon Guillemots, which are a tough bird to find on the SemiPen. The auklet was my 180^th year bird, meaning I had reached my modest target halfway through the year. Two hundred began to feel like a feasible, but still distant, possibility. 

Chapter 5: May

I have a ritual for the first day of each month, one that is practiced by even fewer birders than SemiPen listing. This ritual is the AMAT list, which stands for All the Months Added Together, but can be simplified as monthly life listing. When the month rolls over, I attempt to find all staked out rarities that I have never seen in that calendar month. One of my nemesis birds for the month of May is Willet. For the last several years, one has wintered at Boundary Bay but typically disappears sometime in late April. This year he had lingered into the final days of April, having been seen at Blackie Spit on April 26 and Boundary Bay on April 28 and 29. However, by moving between both locations, the Willet complicated my decision regarding when and where I should look on the first of May. Tides are an important factor. The morning high tide was suitable for Boundary Bay, whereas the evening high tide was not sufficiently high to bring the shorebirds close enough to the dyke for careful study. Such a high tide is not essential for Blackie Spit, therefore, I decided to go to Boundary Bay in the morning, and if the Willet was not there, I figured I could still look for it at Blackie Spit that evening. With this strategy, as long as the Willet stayed at either location for the entire day, I should be just about guaranteed to see it.

While I was at Boundary Bay that morning, the Willet was at Blackie Spit. Adding insult to injury, so was a flock of Gray-crowned Rosy-Finches, another great would-be SemiPen year bird. I could not relocate either bird that evening. A Short-eared Owl sitting in the saltmarsh across from the spit and a Northern House Wren at Dunsmuir Gardens offered some consolation, both being good SemiPen year birds and the owl also being a May lifer. However, that sighting of the Willet on May 1 was the last one of the spring, and so it remains my May nemesis bird.

Things improved on the morning of May 3 when I found SemiPen’s first Black-and-White Warbler at Blackie Spit. My camera battery happened to be dead, but MEHA managed to snap a photo. Good birds kept coming to Blackie Spit. Early on the morning of May 11, while I was at Brunswick Point, a flock of American White Pelicans were found. When I went to search for them the tide had already fallen leaving very little water in Mud Bay. With no pelicans in sight, I continued my search around the bend to Crescent Beach where scoping the tideline many kilometres away I found a different big white bird – Great Egret. It turned out that MITA had actually found it less than an hour earlier at Blackie Spit, but those news had not reached me so I was pleasantly surprised to “find” it on my own. However, it seemed that the rising thermals carried the pelicans away to their next destination.

On May 16, ANFO found a Heerman’s Gull at White Rock Pier; a spectacular spring record. This species is typically seen in Metro Vancouver in August and September after dispersing north from their nesting colonies off Mexico, but in very small numbers and rarely on the SemiPen. On May 17 it was relocated by ROFO and I wasted no time to go see it.

On May 22, while scoping the mudflats from the end of Blackie Spit, I noticed three godwits across Mud Bay that wore a strikingly similar plumage to the three Bar-tailed Godwits that MEHA and I found at Brunswick Point two days earlier. Two birds had rich rufous underparts and one was quite pale, but they were more than 800 m away and details were difficult to discern. Eventually they made a short flight and those views confirmed that they were indeed Bar-tailed Godwits, likely the same ones. This spring proved to be exceptional for barwits in Metro Vancouver. They moved between Blackie Spit, Boundary Bay, and Brunswick Point, with eight at the latter representing an all-time high count for BC. My personal high was five at Blackie Spit on May 28, the same day as an American Avocet. Two avocets were found here by ROFO and PHWR on May 23, but were not seen again until my sighting, which was presumably of one of those two birds. In addition to the barwits, on May 22 I saw two Franklin’s Gulls and two Red Knots at Blackie Spit. On May 29, I saw a Turkey Vulture circling over King George Highway, which would be my only sighting of this species all year.
