Upper Oso Reservoir – Visit on 4-19-14 (Private Access)

(Least) Bell's Vireo (13894)

Monte Taylor and I arrived approximately 3:15pm in hopes to find several of the migrants that typically pass through this area.  Our stay was until 7 p.m. though our success was only moderate, this visit was not in vain.

In all, a total count of 33 species were accounted for including a Warbling Vireo, (Least) Bell’s Vireo, Yellow Warblers (5), Wilson’s Warbler and a male adult Hooded Oriole.  Other birds of note were a single Clark’s Grebe, Hammond’s Flycatcher and an American kestrel.  A complete list can be seen here

Along the slopes were the blooming Arroyo Lupine flowers as shown here in this post.  These are not edible and toxic if ingested to the human body.
