The SCVBA Phylobirding trip to Alum Rock went well, with 39 species from 21 families (including 6 passerine superfamilies). Three species in family Cardinalide, superfamily Passeroidea, were there: we saw and heard a great many *black-headed grosbeaks* , all male; a male *western tanager* (not really a tanager, and it should more reasonably be called a western piranga) sat for photos; and a single female *lazuli bunting* showed herself briefly. We found a *western warbling vireo* (Vireonidae, Corvoidea) nest, with the unseen male single energetically nearby. We had good looks at a *wrentit* , only New World species of the parrotbill family (Paradoxornithidae, Sylvioidea). Thanks to Vicki Silvas-Young for co-leading and IDing all the plants and butterflies.
