Cuck, no, oooo.

Everyone appears to be awaiting the arrival of the Cuckoo this year, and much has been printed on their expected continued decline. The next couple of weeks or so could determine whether Cuckoo is reclassified as Red-Listed. Listen-out.

Of all the disappearing birds, the disappearance of the cuckoo is one of the most intriguing. Its host species are gnerally doing well, so I assume its something happening in its wintering grounds.

Three things are believed to be responsible for cuckoo decline (not counting the shooting arcade called Malta and Cyprus). One is that the three main hosts species for cuckoo - dunnock, meadow pipit and reed warbler are all in decline. That the milder winters have affected caterpillars, which have become more prone to fungus. Cuckoo's need these caterpillars to replace weight and body condition compromised on migration, and lastly longer and more severe droughts in their African wintering areas - affecting both food sources as well as water availability.
Hopefully, being such a charismatic species (much like swallow) money will be found to try and identify the major causes and put them into reverse.
