Howell, T.R. 1950 S. v. nuchalis Dry Lake, 15mi. N. of Princeton British Columbia April 28 (cont'd) tattooed back-and forth on branches of the same tree, the other bird sat by silently. I could not be sure of the sexes of any. Then one of the younger birds flew off, and the other remained tattooing. At 9:55 A.M., it is still there, tattooing, although light rain and hail has come up. I do not see [illegible] or hear any of the others. 10:00 A.M. - I see the "old" bird now - it is about 8ft above the tattooing one, on the same branch. The lower one tattoos about every 45 sec.; in the middle of the tattoo, the other bird gives a brief "roll" of [illegible] its own - quite noticeable, always while the other is tattooing. Between 10:04 and 10:13, one tattooed 20 times. The other bird mostly preened, only once or twice giving a roll, and once while the other was not tattooing. On about the 18th time, there were a couple of tattoos from near by. Between tattoos, the performer just sits. At 10:37 another bird flew up nearby. One of the two flew over towards it, and suddenly there were all four, squawking and chasing. This lasted only a few seconds, and then all was quiet except for some light tattooing.
