Dinosaur Ridge - Denver Field Ornithologists
Colorado, USA
Visitors:
Birgit Arvin arrived just as we were watching the woodpecker. Other people strolled by but no other bird watchers stopped.
Weather:
Today started out sunny and warm with a good south wind. Eventually clouds increased and the temperatures cooled for a very comfortable day. The winds appeared to be forming a vortex over the ridge, Rooney Vally North winds and observation South winds. This unfortunate pattern seemed to discourage migrants from using the ridge
Raptor Observations:
We had a few easy to see raptors early but very quickly birds began flying very high. In spite of excellent cloud cover, we located only a handful of raptors in the afternoon moving very, very high west of observation.
Non-raptor Observations:
Lewis’s Woodpecker perched on the power line pole for several minutes, Pygmy nuthatch, western kingbird, yellow-rumpled warbler, broad-tailed hummingbird, cliff swallow.
