A flock of gulls regularly roosts on Lake Calhoun this time of year, but I was surprised to see a group of 60 or so feeding at the tops of large hackberry trees on the east side of the lake on Sunday afternoon. The berries are on outer branches too thin to support birds that heavy, so they were hovering or flapping their wings while holding onto the twigs and grabbing the berries. Very bizarre and striking, like big white butterflies. I don't see any fruit listed in writings about their diet but, given that they are almost endemic to garbage dumps, it shouldn't have been surprising.
Mostly ring-bills with a few Herrings, nothing unusual yet... Stephen Greenfield Minneapolis [email protected] ---- Join or Leave mou-net: http://lists.umn.edu/cgi-bin/wa?SUBED1=mou-net Archives: http://lists.umn.edu/archives/mou-net.html
