|Brooklyn Bridge Park and Manhattan. Pine siskins have moved in!|
|Little pines siskins, Spinus pinus, are easy to overlook. They are about five inches long and only weigh about half an ounce. They are mainly brown with streaks on body and head.|
|Yellow wing edges.|
Pine siskins eat seeds of conifers like pine, cedar, hemlock, larch, and spruce. They also eat seeds of birch, sweet gum, maple, and alder. And they eat the tiny seeds of grasses, dandelions, ragweed, and other plants. They occasionally snack on an insect or spider. They are happy to come to feeders for thistle and sunflower seeds.
Pine siskins sometimes travel with other irruptive migrants like crossbills, redpolls, purple finches, evening grossbeaks, and goldfinches. Birdwatchers call these the winter finches; I hope to see some of them in Brooklyn Bridge Park, too! But the park has been closed for a week because of hurricane Sandy and has just reopened. I'm on my way out to look for finches. I'll report back.
The siskins may have been carried far away by the storm. (Click here to listen to a short NPR interview describing how birds can travel inside a hurricane's eye.)
