Some good opportunities to study birds on the Pipeline Road this morning including a nice selection of trogons. Slaty-tailed and Black-tailed Trogons could be compared as they 'sang' from the same tree. The orange bill of the Slaty-tailed Trogons could be clearly seen compared to the pale yellow of that of the Black-tailed Trogons. The males were particularly attractive with the white chest line a good feature of the Black-tailed.
