Peteeka 1943 Agelaius phoeniceus. June 17 2 miE Norfolk, 2400ft., Trinity Co., Calif. Four additional blackbirds were noted in the colony this morning. The newcomers included two males, one of which was taken. That these males were not established was clearly evident from their undemonstrative behavior, as contrasted to the behavior of the remaining established male. The unestablished blackbirds uttered only the characteristic red-wing black note. By the other hand, the established male performed hovering flights over the colony and gave his clear alarm-note frequently. One female was also taken. This specimen appears to be a first year bird as it lacks the red tips on the shoulder feathers. Its ovary was inactive; the largest omm being no larger than 1/2 mm. It is, of course, not possible to say whether this female was one of the original 5 females in the colony or whether she was one of the newcomers. June 18. Only one male and one female are present in the colony. June 20. Miller reports that two additional males with the remaining four were present in the cattail pond. These males behaved as unestablished birds, as described above.
