David,
 Perhaps with all the unseasonably warm weather, birders are also out more, and seeing/hearing/reporting more?

Just a thought,

Subject: [MDOSPREY] Early arrivals


Can anyone help me understand why there are so many early arrivals?
Yes, this is a weird year.  It's been a crazy-warm winter and so far an
ven crazier spring.  I understand that birds seeing this warm weather
ay be tempted to move north, start singing, nesting, etc.  So far so
ood.

The problem I'm having is understanding the pattern of early arrivals.
ure, species like Gnatcatcher and Louisiana Waterthrush should already
e in the southern part of the country so they know the weather is
armer than usual and may head north faster.  But species like Wood
hrush and Ruby-Throated Hummingbird spend the winter in the tropics.
 have not yet had the pleasure of meeting a bird that can operate a
eather radio or visit the internet.  They don't know the weather up
ere is warm and they should not be arriving early due to *our* warm
eather.  Yet they're being reported.  Is there something I don't
nderstand?  One possibility is there is always a vanguard of early
igrants but with normal weather, they either starve or freeze before
hey have a chance to be reported.  Other idea?  Data?
