“Cuckoo eggs are able to mimic dozens of other songbird eggs, but each female can only lay one kind.”
– The Titchfield Twitcher
The first cuckoo of Spring,
And the war is about to begin agen
For the dunnock and robin, the pipit and wren –
But the blackbird nests at leisure
Knowing her treasured eggs are secure –
They’ve fought and won this battle before.
For cuckoos hens must lay their eggs,
Their undercover powder kegs, to match
The very nest from which they hatched.
So daughters follow mothers and grans
In their taste of prey that spans way back –
A family tradition in attack.
But not the birds in black.
They know an egg that’s out of whack, alright –
Imposters tossed on sight.
As for the parents, lurking still,
They’re pecked and mobbed until they quit –
A tougher host by far than finch or tit.
Thus all the cuckoos with the genes
To burglarise the forest queens have gone,
Wiped out, were rumbled in their con.
So when these gothic thrushes hear
That goading call – no fear, no doubt –
They just sing louder yet to drown it out.
