Subject: [MDBirding] any research on migrant traps?
I've been wondering why migrant traps -- places that attract a lot of
migrating birds -- are where they are.

I read this nicely detailed description of the maintenance yard area of
Rock Creek Park in DC. It points out the the yard is at the top of a hill
that is higher than most of its surroundings.

Is elevation part of what makes a migrant trap? Peninsulas like Cape May in
New Jersey make a lot of sense, but what about inland. How would one go
about identifying a migrant trap in a place not already widely known. Does
anyone know of any published research on this?

Thanks!
