June 9 II

Bird back at nest covered with damp n.m.  Stands, preens, looks alert and flies off 5:27

Variant of aerial LCN is "hee-ee" almost bisyllabic.  

More birds arriving now. Including courting pairs. 5:33 Courting pairs seem very mobile. Flying away soon.

[[left margin]] !! [[/left margin]] CC. call could be transcribed as very long "how" or "how-ow-ow-ow-ow"  (syllabic division very slight indeed).

[[left margin]] !! [[/left margin]] Watching Swoop-Soar pattern. Usual CC is "haaaaah haaaaah haaaaaah haaaaaah...." changing to shriller "heee-ee-eee Areeeeeee" etc, at climax of charge.

[[left margin]] !!!! [[/left margin]] "Kaaaaah" [[right arrow]] "heeeeeeeeeee" [[right arrow]]  kuh-kh-kh-kaaaaauh" [[right arrow]] "ha-ha-ka-ha-ha-ha" Increasing aggressiveness (Two intermediate stages are not quite comparable.

Still dull 5:57.

Can be "kh-haaauk" or "kuh-kh-kh-kh kauh" etc, as well as "kuh-kh-kh-kh-kh-hanh"
