 Subject: Compiling Late Hummer Dates

Many of you have contributed spring arrival dates for Ruby-throated
Hummingbirds to various Web sites and/or to "Operation RubyThroat: the
Hummingbird Project." Not much attention, however, has been paid to
the fall departure date.

In conjunction with EarthTrek, I designed a protocol through which you
can report late dates on-line--all in attempt to get a better
understanding of when RTHU are where.

I invite all BirdChatters to register with EarthTrek and to report
RTHU departure dates according to the protocols outlined at

  . It's free, and the data you submit are valuable.

The migration protocol allows you to indicate RTHU departure dates by
age and sex, but please note that just because an autumn bird looks
like a female doesn't mean that it is. Some young males have white
throats, no streaking, and no red feathers, so a white-throated bird
in autumn is best referred to as "unknown age and sex." (This is
detailed in my EarthTrek protocols.)

Please forward this e-mail to observers in other states so they, too,
can submit autumn departure dates to EarthTrek/Operation RubyThroat.

Happy Fall Hummingbird Watching!


P.S. Folks in Mexico and Central America are now submitting fall
ARRIVAL dates, using a different protocol.
