As spring gently unfolds her warmth, the species of birds that frequent the backyard feeder are changing with the weather. Certainly, the feeder is still a major attraction. However, the Blue Jays that dominated the daily arrivals just a few weeks ago have now given way to Red-winged Blackbirds and Common Grackles. That’s not to say that the Blue Jays have disappeared, but fewer seem to be visiting. The American Goldfinches, on the other hand, are present in even greater numbers. The males are just starting to show signs of their spring spruce-up as their bright yellow breeding colours begin to replace their muted winter gold. A few days ago, the Goldfinches were joined by a few raspberry-bright Purple Finches. The Purple Finches weren’t regular winter visitors, so perhaps these few are just stopping by on their migration north. The wintering American Tree Sparrows are still here too. They will be leaving for their northern breeding grounds one day soon. I find that they tend to just disappear one day, replaced by similarly-coloured Chipping Sparrows as if by magic. The Chipping Sparrows breed here in the summer and winter farther south.
A few male Brown-headed Cowbirds have been joining the Grackles and Red-wings. I did see a few stray Cowbirds that visited a few times in the winter, but I think these individuals are probably here for the summer.
I like to watch the Grackles pointing. This “head-up” display is sometimes performed by females, but it is predominately a male posture, used both to attract females and as an aggressive signal to warn off other males.
In the photograph below, I caught a Grackle displaying with puffed-up feathers. It’s not clear whether his audience is impressed. The second Grackle looks a bit bemused by this performance, as if thinking “What the heck??” The display is another sign of spring and the new breeding season that is quickly approaching.
