With bright sunny skies and a forecast of 100°, our group of about 20 birders began the SFVAS Hansen Dam birdwalk with guarded optimism. We initially spotted a European Starling, followed by “good” birds such as Vermilion Flycatchers, Western Bluebirds, and striking Red-tailed Hawks. A juvenile Red-tailed Hawk was hanging out in a pine tree giving us a great view.
Many Common Ravens took offense at the presence of the hawk, with one perching directly over it for a prolonged period. There was also a squirrel sitting directly in front of the hawk; it appeared that none of them wanted to expend too much energy.
We reluctantly proceded to the shade structure at the Otis Wallace Children’s Campground (not sure it was ever used as such) and were able to observe large numbers of squawking Cassin’s Kingbirds, a huge kettle of Turkey Vultures, and a couple lively Northern Yellow Warblers (likely experiencing pre-migration zugunruhe ). The walk to the actual dam was rather hot and unpleasant. Surprisingly, there was virtually no water at the dam, with just a trickle coming from the Tujunga Wash We clearly heard a Least Bell’s Vireo singing – they too should be on their way soon to points south. As we neared the end of the walk it was 91°, but to everyone’s delight, we were able to relocate the Vermilion Flycatchers!
I concur with our SFVAS Board member Pat Turner: ‘You know, in spite of the weather, I think that was one of my favorite Hansen Dam walks. I loved overhearing all of the younger birders and channeling their enthusiasm for everything: “LOOK, it’s a Black Phoebe!”‘
Here’s a link to the eBird list for the walk today.
One sad finding: a Common Raven was observed suffering from Avian Pox.
The incident has been reported to the California Department of Fish and Wildlife.
