Subject: [obol] Re: eBird animated maps of avian status & migration
As is true of so many things eBird, not everything is quite what
it seems.

The Rufous Hummingbird map almost certainly reflect the seasonal
movements of Rufous Hummingbirds

but the Mountain Quail map more probably represents the seasonal
movements of bird watchers

Not a criticism of eBird, just a observation as it pertains to
the influence of the observer on data collection and limitations of any
given data set that results.
