Interesting Arrival Patterns

Armchair bird observers know that various species have their own typical pattern of fly-in-and-feast. Chickadees and Titmice, for example, are grab-and-go, flying with pinpoint accuracy. Mourning Doves make a scene as they quite literally crash the party. And there are the woodpeckers. Every one I see, with rare exceptions, seems to need a staging point, as if they can't quite find the feeders. Notice that this Red Bellied Woodpecker is perched on a sunflower seed tube. After reaching this point, the bird studies the local geography and only then hops over to the suet feeder desired. I am fascinated but perplexed by this strange behavior. They all seem to find tree trunks the first time. So why not feeders? More research is needed!
