Very conservative estimate; quite possibly as many as 25 or more. Rough estimate was based in part on the considerable singing and calling of Pine Siskins that were for the most part concentrated in a good-sized, densely-foliaged, Holly Oak, this being the exact SAME tree that Kiandra and I saw and heard PISIs in, this past Friday (2 April)]! A few individual PISIs were occasionally seen flying off from the tree where the concentration of PISIs continued to vocalize (most of these birds buried inside the dense foliage of the live oak, and not in view). In addition, a couple other PISIs were heard singing in nearby trees, and a few (in one's and two's) were seen periodically flying down to get a drink from a leaking faucet that was nearby (giving opportunity for photos). Saw one PISI in a deciduous tree that was just leafing out; the siskin appeared to be probing into the small buds on this tree. Some of the siskins showed fairly prominent amounts of yellow in the closed wing (presumably adult males), while others seemed to show very little yellow in the wing. Otherwise, these were small birds (roughly LEGO in size), brownish above, and whitish below, overlain by very prominent, dark-brown streaking. The bills were, for a finch, relatively narrow and quite sharply tipped.
