'Cu-ckoo! Cu-ckoo!'
One bird that needs little introduction is the cuckoo.
Sadly, however, cuckoo numbers are on the decline and in 2009 it joined the red list of endangered British birds.
We don't really know the reasons for their decline - it could be that the African forests where they spend winter are disappearing, or that the caterpillars they eat are harder to find. It's also possible that with spring starting earlier each year due to climate change that the cuckoo's hosts are breeding before cuckoo's even have a chance to lay their eggs.
However, it's not all bad news - cuckoos are still being heard around the country . Even our new Conservation Director had a recent encounter with one!
So while you're out and about this weekend do keep an ear out for that distinctive 'cu-ckoo' call.

Apart from them heralding Spring for us what useful purpose do they serve in Scotland? How many of our native birds eggs do they kick out of their nests?
A million voices for nature.
Heard a cuckoo this morning in Folkestone alongside railway.
Heard my first cuckoo at Fairburn Ings on 29/04/11
There is a cuckoo @ Mad Bess Woods in Ruislip again this year been hearing it now for a couple of weeks. Never spotted it :-(
Cuckoo heard whilst visiting my parents on Easter Monday - Queen Elizabeth Forest Park between Drymen and Gartmore (Stirlingshire). Also heard, then saw one on fence post in orchard area of Locherwood (back road between Lochwinnoch and Bridge of Weir, Renfrewshire) whilst out with the dog one evening - first time I've ever seen one up close (ish)
