The song and calls of the Copper-throated Sunbirds are not well described. Wells (2007) says “A disyllable somewhat like the Brown-throated Sunbird, but no more detail available, and songs undescribed”. Cheke & Mann (2001) state “A deep trill, more melodious and less descending than the Yellow-bellied Prinia…”. The calls/songs made by males in this recording include: 1. A single, sharp, high frequency (20-21 kHz), brief (0.1-0.15 seconds) call, This call is almost not perceptible to me due to age related high tone hearing loss; hence may be missed by bird watchers. This is the commonest call made by adult males and also used territorially and in flight. It is use repeatedly 1-4 seconds apart for some time. 2. A song/call was heard infrequently and is a drawn out chatter of numerous notes uttered in 4-5 seconds of varying frequencies.

Cheke & Mann (2001) state “A deep trill, more melodious and less descending than the Yellow-bellied Prinia…”. I made 9 calland song recordings of a number of birds over a 4+ hour period. Thecalls/songs made by males include: 1.   A single, sharp, high frequency (20-21 kHz), brief (0.1-0.15 seconds) call, This callis almost not perceptible to me due to age related high tone hearing loss; hence may be missed by bird watchers. This is the commonest call made by adult males andalso used territorially and in flight. It is used repeatedly 1-4 seconds apart for some time. 2.   The less common call heard was the one referred to as a ‘disyllabic call’ in literature. To my ears this is a single note call, lasting 0.3 seconds and issort of a ‘pleading’ call (16-17 kHz). It does resemble the call used by the Brown-throated Sunbird. It was made 2-4 seconds apart, at rest, with a female in attendance. 3.   The third call is what I would consider the bird’s song. It was made not infrequently both at rest as well as when moving about. The song lasts 1.5-2 seconds and is a high frequency (20-21 kHz), has 9-14 notes sung rapidly. I presume this is the one referred to as a ‘trill’.
