Whew! Superb paper! Thanks, Allan, for the reference. Have just finished reading it in its entirety. My head is spinning from all the statistical stuff, but it's clear that while elevation and latitude are key factors in determining what thrush (and of course other) species occur in particular locations, other factors, e.g. tree height, tree diameter, shrubs, etc., play a key role, too, especially at the relatively "low/intermediate" elevations most of us have been posting about in this discussion on this list.

Subject: Re: [VTBIRD] Thrush Topography
Some of the early research on resource partitioning and competition was done on thrushes across an elevational gradient...right here in our backyard.

> With all of the talk of wood thrushes lately, I wonder about thrush species distribution based on altitude. I have always sort of assumed that as you climb from say 300' to about 3,000', Wood Thrushes were at the lowest altitude, followed by Veerys (Veeries?), followed by Hermit Thrushes, followed by Swainson's Thrushes, followed by Bicknel's Thrushes up toward the mountain tops. Is this about right?
