Birders

You have this image of a bird in flight, sitting on a branch, or feeding through the leaves and it gets blown away when you see them this close.

First of all, they are so much smaller than you'd imagine. I held a Yellow Warbler - similar in size and shape to the Wilson's Warbler pictured - and you realize you can hold four of them in the palm of one hand. And they're virtually weightless.

Second, you realize how fragile and how beat up they get during migration. In your mind, you see the bird in the field guide or other photos but in your hand you realize these birds have been through some things. They're flying at night, feeding like mad during the day, and dodging predators. It takes a toll on them.

The people manning these stations are doing great science - checking age and sex of the bird, their relative health, and then banding them before sending them on their way. The bird bands provide a way for other banders to identify previously caught birds and this allows them to piece together some bits of information if they're ever caught again.

If you have a station near you, I'd highly recommend visiting it.
