On Tuesday night, I tried the Christmas Island airport for
nightjars. No response to the call of Savanna Nightjar. But when I
played the call of a male Grey Nightjar, a bird flew straight over my
head calling loudly but its call was very different. I couldn't get
the torch on it fast enough so I did not see it. I could hear it
calling over the far side of the airport, and there seemed to be
possibly a second bird calling.
No response on Wednesday or Thursday night.
But the other people I had been on the Cocos Islands with arrived
yesterday, and we went to the airport at dusk. At about 18:50 after
I had played the call of Grey Nightjar, a nightjar 'floated'
past. It did not call. We did not get on to it. However 10 or 15
minutes later it flew past again. Again, it did not call. This time
we got a small LED torch on it. No easily discernible markings. A
medium sized nightjar. We waited about another 20 minutes but did
not see it again.
We finally quit and had dinner, and then returned to our
accommodation and grabbed our respective field guides of Asian
birds. All six of us came to the same conclusion that it was a
female Grey Nightjar. The SE Asia field guide by Robson notes that
the female Grey Nightjar makes a different call, and the
'description' of the female call is the only nightjar call described
in our field guides that could be interpreted to sound like what I
heard. I am the only one who heard it call. I have used Google to
try to find a recording of a female. xeno-canto has 15 recordings
but they are all of males (two had the 'Darth Vader' calls of a
hawk-cuckoo in the background).
Does anyone know where I might find a recording of a female Grey Nightjar?
The female Grey Nightjar is the only one mentioned as having a different call.
Does anyone know if females of other nightjars call
differently? e.g. Savanna? (has been found on CI before but this
bird was larger than a Savanna). Large-tailed? (But I would have
expected one of us to see some markings on the tail if not the buff
wing patches). Indian? (same about markings). Malaysian
Eared? (also no clear markings other than pale collar which maybe
one of us could have seen but noone did. also not
migratory?). Great Eared? (far too small for this species). Any
other nightjar that could migrate to this area? Grey Nightjar
migrates to Sumatra and Java. It is a 'jungle' nightjar, and this
bird was flying over the vegetation rather than the open grassy areas
of the edge of the airport runway.
I head back to Perth today, but hopefully the others will get more
details in the next three nights.
