C. rufigula x zonatus May 91 More random notes: (1) Rufigula is not wary & if approached slowly will feed a few feet from the observer, while zonatus cannot the approached closely, flying off excitedly whenever the observer is detected. Rufigula makes short flights to thick brush when disturbed while zonatus may move in a long flight 50-100 to a tall tree a palm. (2) Rufigula is most commonly seen 5-10 feet above ground & often lower than 5 feet. Or sings from an exposed position &d while not always from highest part of tree it is invariably in an open place, either on a deciduous limb or a dead limb. The tal is not joined out usually unless & is at side of & they are calling together. I have not heard & & due the same call - always 2 calls given at same time - that of & being soft & harder to pick out of the combined call. (3) Rufigula occasionally descends to ground but even when foraging the ground it perches on a twig, sees an insect on ground and then descends to pick it up rather than hunt on the ground. I have never seen zonatus below 6 feet & usually they are foraging high (+15 feet - up to 35-40) in the taller trees).
