One of my favorite things is to watch a really active feeding station. Even if it's birds I've seen a bazillion times, I love watching bird feeder activity, especially in winter before we get a snow and birds are coming from all different directions. Tuesday had subzero temperatures and the start of snow fall and birds were ready to take advantage of a feeding station. I laughed when I arrived at the Minnesota Valley NWR visitor center because of the turkey activity. Note all the turkeys on the ground and all the songbirds crowded into the feeder on the right. Now, note the turkey on top of the feeder on the left...and now songbirds!
It was fun to watch the large bird balance its body and avoid sliding as it went after the food in the platform feeder. Periodically the turkey would slide down and then feed on the ground for a bit. But soon it would again try for the food on the feeder. The activity of all the birds and the snow was intense. I tried to get a video:
It was a steady stream of turkeys, house sparrows, cardinals, blue jays, woodpeckers and chickadees.
Some of the turkeys would just park themselves right next to the windows and sit there. I'm not sure if the bird was looking at its reflection or feeling some of the heat off the building. I've always found it curious that turkey vultures migrate out of Minnesota, but wild turkeys stay. Turkeys have bald heads, but they do have some bristly feathers and from the above photo, it looks like those are enough to keep them off the face.
A big surprise to me was a small flock of about 16 brown-headed cowbirds hanging out. They really looked like they were hating life. I'm sure they were asking each other, "Okay, who had the brilliant idea of not migrating because it would cost too much energy and be dangerous?" The mostly stuck to roosting in the trees and the few who came to the feeders were not their usual bossy selves. They were slow and lethargic. One lone male kept feeding on the ground and almost got stepped on (or tasted) by a turkey.
I like sit on the visitor center on cloudy days in winter. If you sit inside you can watch the feeders without the sun directly behind them. So, I was able to sit inside, get some decent photos, and stay warm.
One challenge is that the heaters are right next to the windows, so you do have to deal with a little heat shimmer, but that combined with the snow can make for some arty photos like the above digiscoped image of a female cardinal. And though the birds were active at the feeders full of sunflower seeds, there was plenty of other food around:
Tree sparrows (above), cardinals, and juncos were feeding on seeds in the grasses. It's a myth that if you start to feed birds in the fall that you have to do it all winter or they will starve to death. They find plenty of food in plants that we look at and see nothing. I think that falsehood was started by some seed seller out there to try and keep his customers coming all winter.
If you have to go for a bit without feeding the birds, they will get over it, some birds like the above blue jay stash food away in a cache for just such an occasion. That said, birds may not visit your feeder as regularly as one that is always filled, but they will come back and they will not starve. They treat your bird feeders the way we should treat fast food restaurants. It's a convenience, but not a sole source of food.
