Icterus cucullatus
12 June
Berkeley, Alameda Co., Calif.
After seeing a male of this species (for about 3 minutes) in an Elm tree about 8:30, I went to check the Washington Palms at the corner of Bonita and Berkeley way. A nest was found and then a female flew from another palm. A male then landed on the telephone wire on which the female was sitting, and was observed lengthily. A second nest was then found. The male was observed to fly into, and later out of this nest. Many House Finches also inhabit these trees. The nests are almost invisible, except from directly below the trees. They are built under down-hanging palm fronds, apparently a shallow oval-type constructed of long, yellow-brown grass, most of which is finely woven into a ball-like shape.
Perhaps only one nest inhabited. (NOTE: 2 males of this species were seen in Tilden Park near the Brazilian Gardens on 10 June of this year--see Journal).
