California Jay
May 1, Querno Rd., Berkeley, Calif.
Brown Towhee heard in extreme alarm from Laurel Tree where location of their nest was suspected to be. On arriving near the spot, one bird called continually and some combat underway. After few seconds, male Jay came out, flew [illegible] carrying egg. Female (smaller) perched nearby, and remained. Male Jay returned, scream-alarm notes resumed by Towhee (one in particular, apparently?), and no few seconds, Jay came out with a second egg, again flew down slope. No further activity by Jays.
Alarm notes of Towhees attracted two neighboring pairs of Towhees, which came within 20-30 feet of tree in which nest predation occurred. Feathers and disheveled plumage of the calling Towhee clearly indicated some fighting between the Jay and the Towhee had occurred.
W.L. Thompson reported seeing a Jay carrying a Robin's egg this past week.
