Mixed Diglossini, Apr. 4, 1963, IV [[circled]] 20 [[/circled]]

intra-specific territorial dispute among the Bruns. Remarkable!

[[margin]] Brun [[/margin]] Another single Brun in Eucalypt, 15 ft above ground.

Are the birds here not associated in pairs? Or are pairs relatively less common here now.

[[margin]] Brun [[/margin]] Still another single Brun in low scrub 4:55.

[[margin]] Brun [[/margin]] These birds here also seem to ignore the [[underlined]] C. homochroa [[/underlined]], again without ever coming close to them. Why? [[underlined]] Is this a specialization [[/underlined]]? Or has each individual Brun learned that the homochroas are "unimportant."? Or is this "ignoring" simply characteristic of most inter-specific reactions of the species? Or what? [[underlined]] This must be analyzed. [[/underlined]]

[[margin]] Brun [[/margin]] 5:30. See a single Brun, apparently feeding on yellow daisies (sic!) in low scrub. This is probably the bird that supplanted the Thly yesterday

Still no sign of the Thly itself however. Do members of this genus have to have comparatively large territories (like some Conebills)?

[[margin]] CC Brun [[/margin]] Aha! See single CC in nearby and similar area. Picking insects off stalks in low scrub. Utters "Seeet" Notes in flight. Also brief "Greeting" phrase when landing apparently alone. Then the bird flies into what must the edge of the adjacent Brun area. Can't see Brun now. Then bird disappears. Certainly not attacked by Brun.

[[margin]] CC Brun [[/margin]] Still no doubt but that CC's are much rarer than Bruns in this environment

Transcription Notes:
In a previous page author used "Thly" as a shorthand for Thlypopsis – a tanager genus
