[EBB Sightings] Saturday morning (4/26) @ Tilden

Except for a single Western Tanager that I barely heard, there wasn't 
much in the way of migrants at Jewel Lake/Tilden Nature Area Saturday 
morning from 0730-1000. That being said, riparian-obligate summer 
residents were in full song with the following approximate numbers 
observed (i.e., heard and/or seen):

Pacific-slope Flycatcher - 5
Warbling Vireo - 20+
Swainson's Thrush - 3 (calling, no full-on songs yet)
Wilson's Warbler - 20+ (easily the most abundant species)
Orange-crowned Warbler - 6
Black-headed Grosbeak - 13

I also stopped by Inspiration Point to follow up on the recent sightings 
there. The Olive-sided Flycatcher was singing from the distant ridgetop 
northwest of the parking lot when I arrived  at 1015, and was singing from 
the Monterey pine grove south of the parking lot when I left around 
1100. I heard, then briefly saw, a single MacGillivray's Warbler in the 
same area first reported by Denise Wright last week (along Curran Trail 
just below its junction with Meadows Canyon Trail) from ~1040-1050. I 
was in the area for ~15 minutes before it started singing, however, and 
it was silent once again as I left the area  at 1055. Its main singing 
perch was the single eucalyptus in the middle of the scrub, downslope of 
the trail. Also of interest was a LAZULI BUNTING pair in a small oak at 
the base of a Monterey pine on the north side of the Curran Trail, ~150 
feet down from the top of the trail  at 1018. There was no sign of the pair 
as I walked back up the trail to the parking lot at 1100, however.
