Mixed Diglossini, Apr. 5, 1963, VII. [[circled]] 27 [[/circled]] [[margin]] Brun [[/margin]] on top of the bird before it became aware of my presence. It uttered "Taz[[underlined]]eee[[/underlined]] taz[[underlined]]eee[[/underlined]] taz[[underlined]]eee[[/underlined]] taz[[underlined]]eee[[/underlined]]" as it flew. This is presumably purely hostile song, with exape predominant. [[margin]] Brun Pect [[/margin]] If the behavior of these birds this morning was typical of their subspecies, I can certainly understand why Pects are relatively rare!! The usual relationship between the songs of the 2 forms may be represented by the following diagram. [[diagram]] [[key]] Brun = [[4 short squiggle lines with breaks in between]] Pect = [[long continuous squiggle line]] time -> [[/key]] The general layout of territories may be shown in this way. [[margin]] Brun Pect Cy [[/margin]] [[top and bottom have long continuous lines with squiggle with "Ridge" written on top of the lines]] [[under ridge is a squiggle line with 2 straight edges on each side going in a slight bend down the middle from top ridge to below the bottom ridge with "Path" written to the right of it]] [[to the left of the path is a dotted dividing the area between the ridges approximately in half - the top area is labeled "Pect Territory" and the bottom is labeled "Brun Territory"]] [[in the Pect Territory there is a blue dot right above the dotted line with an arrow pointing to the left. There is also a green dot slightly above the dotted line to the right of the blue dot]] [[There is a red dot in the middle of the Brun Territory]] [[To the right of the path between the ridges are the words "Possible 2nd Brun Territory"]] [[/diagram]]
