Xanthornna yrcas Feb 27. Santa Ana Wildlife Refuge In newly-leafed trees around headquarters - seems to be paired. Saw one fight between two birds. One call sounds like "eek eek eek"; another like the "kuk kuk kuk" of the Steller Jay. I have heard also a call "kera a aa" a prolonged frog-like woak identical to a similar call of Aphelocoma coerulescens. Feb 28. Call like rusty gate-hinge given by bird this morning: kra a aa eee the latter of brass quality. The "eek- eck-eck" I heard given alternately by two birds, one somewhat higher-pitched than the other. Mar 1. At 2:45 pm (clear, windy) a congress of not fewer than four Green Jays were in a large broad-leaved tree the trunk of which was hollow and perhaps 30" in diameter (each of 2 main forks). The jays kept up a constant "eck eck ek" the din being interrupted momentarily only when I walked over to investigate. Some of the voices were definitely higher pitched than others (more nasal, less rushing). Mar 5. Arroyo S J Harlingen, Cameron Co., Texas - overcast, calm. 4 Green Jays in mesquite patch. One flew 50 yards across opening calling "cluck cluck cluck". 2 then last followed as they flew first bridgave "rusty gate" call kera aa aa.
