    Equipment Note

NOTES: Weather: WIND; NEST ABOUT 25FT UP AGAINST THE TRUNK OF A 40FT JACKPINE. YOUNG DOWNY WHITE WITH SOME GREY DOWN - ABOUT PULLET SIZE. YOUNG CROUCHED DOWN AND REMAINED QUIET WHILE THEY KNEW WE WERE AROUND, BUT THEN STOOD UP AND WALKED AROUND ON NEST AFTER WE HID 2 NESTLING(S); 1 ADULT(S); Sex: UNKNOWN FOR A WHILE. MEANWHILE THE ADULT WAS OFF HUNTING, AND DIDN'T KNOW WE WERE HIDDEN IN THE UNDERBRUSH ABOUT 50FT FROM THE NEST. ADULT LANDED AT NEST WITH FOOD WHILE YOUNG BEGGED, THEN SAW US AND FLEW TO ANOTHER TREE CALLING (ALARM OR THREAT CALLS). MATURE

[These are primarily "kak, kak, kak..." Alarm Calls (sensu BNA). They appear to be deeper than those in some recordings, suggesting a female bird. Initially, there are a few soft squeals of the nestlings. Quality changed from 1-3 to 2, 1-2 (1-2 for most of the latter half of the recording)- CAM - 24 November 2004]
