I'm with Margaret on this being a mixed icterid flock. The icterid family includes blackbirds and grackles. To narrow it down further, I wonder if the observer noticed the shape of the birds - whether they had relatively long or short tails. Short tail would point to starlings, longer tails would be blackbirds or grackles. Wendy Ealding It is probably a mixed flock of starlings, red-winged blackbirds, and maybe some grackles. Margaret Would anyone have any ideas on this? ----- Original Message ----- From: _Moore_ (mailto:bobbim@xxxxxxxx) To: _audubon@xxxxxxxxxxxxxxxxxxxxxxxx (mailto:audubon@xxxxxxxxxxxxxxxxxxxxxxx) Sent: Sunday, August 07, 2005 4:42 PM Subject: Migration question If possible, I would appreciate an answer to a question, or direction to where I could find the information. This evening, August 7, 2005 around 7:00 pm, we observed thousands of birds flying north, then north-east. This lasted for over 15 minutes. The main group (thousands of birds) took about 8 minutes to fly over, then the stragglers took up the remaining time. I do not know the species, I could only tell that they were very dark - I could not see any color. The size was smaller than a crow, but bigger than a wren. The song we heard was only a single "Cha" sound. I realize that this is not much detail, but we have never seen this many birds flying over in August. We live in Halifax, VA, about 30 miles east of Danville, 50 miles north of Durham, and 115 miles south-west of Richmond. I would greatly appreciate it if you could help me.
