I went to John Nicholas Trail this morning hoping to find a Wilson’s
Warbler. I heard one as soon as I parked my car in the parking lot on Black
Road, but I proceeded to take the trail to Lake Ranch Reservoir to see what
else I could find. There were eight more Wilson’s Warblers singing along
the trail to the lake, and at least four at the lake. Other spring migrants
singing along the trail were Western Warbling Vireos and a Western
Flycatcher.
At the lake, near the far picnic table, there were two Cassin’s Vireos in a
willow tree and a Black-headed Grosbeak singing nearby. Other highlights at
the lake were a pair of Hooded Mergansers and an adult Bald Eagle catching
and eating a fish.
When I got back to my car, I heard another Cassin’s Vireo.
