August 19

On August 19th I set out early in the morning to start the first day of fall migration monitoring at Haldimand Bird Observatory’s Hurkman’s Farm. The morning was cool, hazy and cloudy but there were a few birds to be caught. Mostly local summer residents, but a few migrants at the end.

I noted at least 8 Bobolinks flying over, which gave me hope for my new project that I would be starting the next day to monitor Bobolinks as they migrate south, like some other banding stations have been starting to do.

Cathy from Haldimand Stewardship and George from the Niagara Bee Group visited mid-morning to meet and take a nutritional sample of the Prairie Grasses. They were both exceptionally pleased with the progress made and gave much praise to HBO for our dedicated work for conservation and education.

August 20

On the 20th of August, the weather was much sunnier, although still chilly in the morning. The strong North winds the night prior pushed a handful of migrants onto the property, a few of which found their way into our nets. Early in the morning we opened the newly placed Bobolink net situated on the path through the prairie grasses, and started a playback that would continue through the morning. Almost instantly we saw a Bobolink fly in, so we quickly left the area with our hopes high of capture.

In terms of the migration nets, the morning was productive for both numbers and species. We were delighted to catch two migrant warbler species – a young Magnolia Warbler and a young Northern Waterthrush – as well as an adult Blue-gray Gnatcatcher, and five hatch-year Rose-breasted Grosbeaks all captured from the same net.

Just at dawn, we were delighted by droves of blackbirds leaving from their roosting area to the east of the property, and we estimated about 1000 of them, mostly Common Grackles. A pair of Sandhill Cranes gave us excellent views as the flew and called over the prairie field mid-morning. We observed 50 species the whole morning which is quite impressive for this time of year.

Back to the Bobolinks! We captured 10 in total for the morning and observed a total of 50, many of which were sitting around the net at the first net check. Ideally, we will add another net with the current one to increase our rate of capture. As they are a species at risk in decline due to habitat loss, monitoring Bobolink migration could be a very valuable program for Haldimand Bird Observatory to facilitate. With any luck, some of the attracted Bobolinks will return in the spring to nest in the prairie field.

Lowville, April 7
We had an awesome first day of banding at Lowville with a total of 27 birds caught (18 banded and 9 recaptured). For an early season day we had a decent number of birds and good diversity. The highlight was a Sharp-shinned Hawk! Although we get a fair number of them moving through during migration, it is rare that we catch these small forest hawks. But it does happen on occasion, and wow what a fantastic surprise it was to find him in the net! What a great way to kick off the season!

April 10 and 11, 2022 : A Diversity of Birds and Birders
On Sunday, April 10th I set out to band with David Brewer, Liam Thorne and Sam Lewis. David is a Master Bander, who has made countless and notable contributions to the conservation of birds and probably needs no introduction. Liam is in Grade 8 and Sam is in Grade 9 and represent two of our young and keen birders. I confidently predict that our young volunteers, including these two boys, will one day become movers and shakers in the field of bird and wildlife conservation.
The weather was less than ideal. Shortly after opening we had to close the nets due to heavy snow. Thankfully, the snow disappeared, and warming temperatures allowed us to safely reopen. What with the migration just getting underway and the mid-morning closure we didn’t expect large numbers of birds. Nevertheless, we did experience a lovely variety of species including:
1 Black-capped Chickadee,
1 Winter Wren,
1 Song Sparrow,
3 Golden-crowned Kinglets (all male),
1 Brown Creeper, and
1 American Goldfinch.

We also recaptured:
1 Black-capped Chickadee,
1 Northern Cardinal,
1 Hermit Thrush

That makes for a grand total of 11 birds, with 8 banded and 3 recaptured, representing a total of 6 different species.

Hermit Thrush

Interestingly, the Hermit Thrush had a lot of fat on him. We suspect he was using the Lowville area as a staging ground to fuel up for further travel up north.

On Monday, April 11th, I returned to band with Ashley Jensen, Dave Maida, Patti Murphy and four more women I met through birding walks at the Royal Botanical Gardens. Ashley, our Bander-in-Charge, has 10 years of banding experience and completed a Masters in Ruffed Grouse population genetics. Dave had a career in forestry management and has been a banding volunteer since 2017. He is also an HBO Council Member. Patti has been practicing veterinary medicine for 32 years, and with retirement around the corner, she is interested in learning to become a scribe.
At 8 am, Pat Turner, Barb Dermott, Suzanne Batchelor, and Judi Dunn arrived. Pat is a former banker and risk management analyst for Bank of Montreal. Barb is a former retail manager and a marketing and communications specialist. Suzanne is a former chemical analyst for Environment Canada and Judi is a former warehouse manager for Hyundai. This was their first time at the Lowville Banding Station to experience songbird banding.
The day’s weather brought a welcomed contrast from the day before with warmer temperatures and blue skies. Again, the bird numbers were somewhat low, but with local and early migrant representation, we enjoyed much diversity.

We banded 18 birds:
7 Golden-crowned Kinglets,
3 American Goldfinches,
1 Slate-coloured Junco,
1 Song Sparrow,
2 White-throated Sparrows,
1 Fox Sparrow,
1 Cedar Waxwing, and
1 Northern Cardinal.

We also recaptured:

4 Black-capped Chickadees,
1 Downy Woodpecker,
1 White-breasted Nuthatch and
1 Carolina Wren.

We had 25 birds altogether representing 12 species. The recaptured birds could all very well be local to the area. The White-breasted Nuthatch was a healthy female aged as an “After Second Year” (ASY). This means the bird is at least 3 years old but could be more. When she was released, she flew up into a nearby tree to rejoin her mate who appeared to be waiting for her there. Interestingly, her mate was recaptured a few days back and he is also a healthy “After Second Year” bird. They could very well be a long-standing couple. Once reunited, they instantly began chattering. We could not help but imagine that they were sharing their banding stories and were especially happy to be reunited. The exchange lasted only a few seconds and then they were back to the important activities of the day, foraging and family planning. We all stood and watched this endearing reunion in awe.

Cedar Waxwing

The special lesson of the day was ageing and sexing a Cedar Waxwing. One of the key characteristics, among others used, was the 8 red appendages indicating that this bird was an after second year (ASY) bird, according to Pyle.

These two days provided a chance to pay close attention to some key local and early migrant birds, each with their own story and unique characteristics. Our banders and visitors, also each with a unique background and life experience, converged here, at the Lowville Banding Station, to share their fascination and deep passion for birds. The bird numbers were low, but the diversity of life was exceptional.
By Catherine Manschot, Volunteer, Lowville Banding Station

As I’ve tried to point out in the last couple of postings, migration is a difficult time for birds. Mortality is high especially with estimates as high as 80% of young (Hatch Year) songbirds don’t survive their first year. I just finished a paper whose authors studied populations of Black-throated Blue Warblers both on their breeding grounds and in their wintering grounds. As the birds stay in place once they reach these areas they are referred to as their “stationary periods”. The authors noted that “apparent mortality rates were at least [italics mine] 15 times higher during migration compared to that in stationary periods and more than 85% of apparent mortality in [Black-throated Blue Warblers] occurred during migration.” And similar findings could be made for most songbirds.

Still, every Spring colourful migrants show up speeding their way to nesting grounds. So some are successful. For these birds everything fell into place: good nutrition at the right times; predator avoidance; sustaining and restorative resting/feeding areas on route; good weather and helpful winds; a patch of desired habitat when they made it home.

Sometimes birds do the right thing, elements are falling into place and they should be successful but meet with…how else can I describe it…simply, bad luck.

I have been aboard the CCGS Hudson for the past month doing AZMP surveys in the lower St. Lawrence River and Gulf of St. Lawrence. [AZMP stands for Atlantic Zone Monitoring Program and consists of comprehensive oceanographic surveys in the Canadian Atlantic.] We were just finishing our area – the Quebec Zone (there are a number of zones in Canadian waters) – and were about to enter the bay surrounding Sydney, Nova Scotia when we “got the call”: there was a vessel in distress about 250 nautical miles (NM) out in the open Atlantic SE of Newfoundland.

The Hudson wears two hats: it’s a research platform for Oceanography (Beford Institute of Oceanography, Department of Fisheries and Oceans, and several others) and it’s a coast guard vessel with SAR (Search and Rescue) responsibilities. SAR takes precedence over research. As soon as we got the call the vessel made a hard turn to port and we were headed offshore steaming at 14 knots, pounding into 4-6 meter waves. [I still did my counting but it’s awfully hard to see birds through salt spray pelting the windows.] Just after midnight we came up with the ship – Fishin Fionnatic (pronounced Fanatic) – a small (15 m.) fishing boat that had been hit by a “rogue” wave and had its port side windows stove in. The crew had been able to clear the lower decks of water and it was able to putt along under its own steam at a steady 7 knots. Even so, we escorted it all the way into Canso. That was bad luck. But the boat wasn’t migrating….

However, when we were still 73 nautical miles east of Canso I watched a BALTIMORE ORIOLE fly onto the ship from over open water. It stayed on the vessel, hunkered down under some machinery, obviously resting, head back under its wing. Shortly before it got dark, when we were still 23 NM from shore, I saw it fly toward the back of the ship but never saw it again after that. I didn’t find it on the deck the next morning. So it likely flew away from the ship…whether it was successful reaching shore I can’t say. But, to me, this was a case of a migrant (orioles winter in Central America) running into some bad luck. There had been a big storm, a low pressure system with counter-clockwise winds, on the eastern seaboard of the U.S. I’m guessing (but am pretty sure) that this bird got caught up in the storm as it was flying south and was sucked up and blown well to the north before it found our “island”. Just another of the trials that migrating birds must endure. And with the climate changing as it is, birds will be experiencing more of them.
