May 27th – New Record!

Records are made to be broken….so it’s said. But after banding 117 Baltimore Orioles last year, 66 more than we had ever banded before n a single season, I thought that record was pretty safe. Sort of like Wayne Gretzky’s hockey scoring records. But as of yesterday we were actually tied. Surprisingly there wasn’t much action at the oriole jam feeder this morning; the birds are getting down to the serious stuff – building nests and raising young, the reason they make the long trek from Central America in the first place. By closing time we hadn’t caught a “new” (i.e., unbanded) oriole. When we went to close nets 1 & 1A we found 3! This pushed the record to 120!

SY-Male Baltimore Oriole – breaking the banding record of 117 set last year – this is #118. -DOL


This SY-Female extended the BAOR banding record to 120! -DOL


Otherwise it was a pretty bland, one might almost say boring, morning with net rounds carried out in ever-increasing heat. The one BIG surprise was the Great Egret that Liam saw when doing census. It was flying south down the river.

Black-capped Chickadees at Ruthven have become very quiet and hard to find – must be sitting on eggs. -MMG


Although we banded only 1 Cedar Waxwing today we counted at least 90 – they are arriving back in swarms. -MMG

May 26th – What Happened To Spring?!

It seemed to take forever before we got “seasonable” Spring weather. During those few days the long-distance migrants we had so anxiously been awaiting blew through. And here we are: right in the middle of Summer temperatures. What was the high today? 32? 37 with the humidex? Yikes!

Opening the nets before dawn has been pleasant – nice temperatures, stars high overhead and the start-up of the “dawn chorus”. It’s fun to try to pick out (and count) all the various species as they come alive with the coming sun and want to make their presence felt. And then POW! – the sun clears the horizon and all hell breaks out with birds chasing each other to declare who owns what territory and to dominate particular mates. By 8:00 o’clock you can feel the heat. The chasing doesn’t slow down….but the net rounds seem to. By closing time (around 11:00) the heat is hard to bear and you’re sweating like crazy (I was going to say like a fat pig but thought that might be somewhat…..offensive to some).

Most long-distance migrants that are going further north have already done so. There are still a few stragglers but the vast majority is well north of us. But migrants that will breed in the area – or will try to breed in the area are still arriving in good numbers. A lot of these are females; eg., we banded 8 Yellow Warblers this morning – most of them were females (young or SY females at that); the 5 Indigo Buntings we banded this morning were all females. And we’re still getting Baltimore Orioles! The 4 we got this morning pushes our total to 117 – tying the record set last year (one I thought we wouldn’t top).

May 24th – Second Wave?

The treat of the season: female Cerulean Warbler. -KMP


Just when I thought the season was winding down…..we had a busy day. Lots of bird activity around the site. The highlight would have to be the female Cerulean Warbler I found in net 4. We’ve only seen a few of these in our 25-year history here so any Cerulean that we get is a treat.

Cedar Waxwings. The male (on the right) is feeding the female. -MMG


Yesterday we banded only 1 Baltimore Oriole but today they were back with a vengeance – we banded 12 bringing our total up to 110, just seven shy of the record that was set last year.

Covid-19 has greatly reduced the number of people using the park. One of the readily noticeable results is the number of animals that we see. Deer are birthing their fawns within 300 meters of the banding lab; raccoons and foxes are around; there’s beaver in the river. Good things are happening. Just have to get rid of those pesky humans…..

May 23rd – The Wheel Is Coming Off

Thanks to Darren O’Neil


When I was a kid, our family would make a yearly hike along the railway tracks from west Hamilton to Dundas. Every now and again we’d have to “get out of the way!” as a train approached. What a feeling as this oh so powerful machine rushed by within a few meters of us and then….the wind and silence as it disappeared around the bend. This is what today felt like: The train, that was the massive movement of migrants heading north, has rushed by leaving the relative silence as it recedes into the distance.

We had such a lousy Spring – cold, wet, windy. It held up the migration. But as soon as the conditions became favourable the birds, feeling the need to get going (they were late!), blew by in a matter of a few days. Whew! I can only imagine the mass of migrants that flew over each night while I slept; it must have been awesome. But now, things are winding down. We weren’t nearly so busy today as we were yesterday or, even more so, the few days before that. Oh, we’ll still be getting migrants for the next 2 weeks or so but not nearly in the numbers that just went through.
