Cobirds:
Green heron spotted at Cottonwood Marsh (Walden Ponds) in
Boulder today, right along the boardwalk.
All the major players are back in Boulder County for the
most part. Only things I haven't seen yet are poorwills and
nighthawks.
A couple interesting things of note: a yellow breasted chat with a
rich orange throat seen near Gregory Canyon (oriole-orange color).
Web sites mention that this is either a morphological difference or
due to diet.
Chases and fights:
A MacGillvray's warbler hammering a spotted towhee
A Broad tailed hummingbird chasing a blue-gray gnatcatcher
A western tanager bashing another western tanager
A female lazuli bunting pounding a male lazuli bunting
A red winged blackbird harassing a pelican
