Cold nights and favourable winds are pushing migrants out of the north. The last two mornings have been cold producing frost patches and, in a couple of places, freezing nets shut. Interestingly, on these mornings it’s pretty quiet and you might think that there aren’t many birds around. But as soon as the sun clears the horizon and produces enough heat to dissipate the frost, the birds “wake up” and begin the day’s foraging.
There is constant activity as sparrows jump up out of the tall grass, fly a few meters and then drop back into it. Or…they might fly into the wetland/forest edge habitat to let things digest before continuing to feed. We’ve moved a couple of nets around to try to intercept them where we’ve seen them moving consistently. But over the last couple of days there’s been a LOT and we’re only catching a small percentage.
As I mentioned, most of the captures are sparrows. Warblers have just about run their course and most are thousands of kilometers to the south of us (hopefully avoiding hurricanes Helene and Milton). There’s still some Myrtle and Palm Warblers but they tend to stay higher in the willows.
