94 95 HAYDOCK MELANERPEs FORMICIVOROUS 1500. HNHR 19 April 16:42 Woodpeckers in tree - did not see any in rest hole. Stores remaining. 10 May 9:30 - 3 nestlings (NOT MARKED) 20g, 20.5g, 21g. 14 June 11:40 - Checked holes in main nest tree - nobody seen. Some acorns remaining 23 June 11:00 - Checked holes in main nest tree - nobody seen 30 June 11:50 checked holes again - hello ?? - nobody. 1995 1 April 11:35 - Plenty of stores. Saw no birds. 17 April 11:40 - Checked holes - nobody seen. 23 April 17:00 - Decided to try removal experiment in this group. Will be removing Bf - to promote replacement and to create group with co-brooding B's. After climbing tree to set ambush, I discover 1 egg (unincubated) and decide not to set ambush. After talking with Walt we decide to delay removal. Part of the problem is that Tim reported 6 birds roasted here last night (less than on field list) so we are not completely sure what group composition is. Tim will observe tomorrow to determine: ① if female lays another egg ② identity of all birds in group 24 April 10:30 - 3 eggs, cool. Set ambush for catching 9 when she enters nest tomorrow after egg laying. 27
