For the coming 2012 spring period it would be great this practice continues and so once again please can members kindly report dates of first heard cuckoocalls on the BBS. Please note it is only the date of the first call in Hong Kong for each species which is needed; Common Koel, Plaintive Cuckoo, Large Hawk Cuckoo, and Hodgson's Hawk Cuckoo. i.e. there's no need to post up the 2nd/3rd.... call for each species.
Same as before, if any member can dig out calldates for any of the years between 1990 to 2003 it would be much appreciated.
Many thanks,

A couple of basic graph is plotted with the above data.
These graphs are only very early draft and include ALL calling dates (include “warm-up” calls?) for these 2 species.
Conclusion is yet to be made but continuous collection of data would give us more clues.

Plaintive Cuckoo singing at Sha Po 13 March 2012.
The report of Indian Cuckoo is interesting. These are not usually present until April - the latest bird report gives the earliest date on record as 10 March, so a January record would be exceptional. I've heard Black-throated Laughingthrush mimicking this speciesa few times - would that be a possibility in this case? Author: cgeoff Time: 14/03/2012 17:29
John,
I think you mean 10th April for the earliest Indian Cuckoo record in the latest HKBR.
But you're right. A January Indian Cuckoo is unprecedented. I've heard laughingthrushes imitate the calls of a number of Cuculus species in HK, and I would imagine this is what happened in this case.

Actually Geoff, I did mean 10 March; I was referring to the earliest on record in the introductory text for the species. Even this seems exceptionally early to me. You are correct that the earliest recorded in 2007-08 was 10 April, which is a more typical date for the first record. Author: kkitty Time: 14/03/2012 18:35

Plaintive calling in Lam Tsuen this morning, 18 March, at least three. Mike Kilburn may have heard them before but these are the first I have heard calling properly.
