Koel in Monash

["Philip Veerman" <>]

Hi Jack,

 

I suggest read the reference and or look at the graph in the GBS Report. As the January abundance is about half that of December, observations in January could hardly be described as "very few". Indeed January is the month with the second highest abundance for the species locally. Although that applies to GBS data over all of Canberra and you may only be referring to Weston Creek (although I don't see why that should be any different). Also the GBS Report and observations do not differentiate between heard and seen observations. More to the point, the GBS Report covers just the first 21 years, during which and clearly since, the Koel has been on the increase locally. Therefore the baseline information (as shown in the GBS Report) is still being established. Also as a corollary of an increased occurrence and abundance, it is reasonably to be expected that the period of weeks per year that it is recorded here would also have increased, from whatever was known or recorded "previously".
