Answer: A – Cetti’s singer
Found in Britain, the Cetti’s warbler is a medium-sized warbler found in willow thickets, bogs and nettles.
It is more heard than seen, notable for its loud, bubbling song, according to Wildlife Trusts.
Cetti’s warblers lay 4-5 brick red eggs which are incubated by the female for about 16 to 17 days.

Answer: A – Guillemot
Murres, also known as ‘flying penguins’, are black and white seabirds often found in droves on the edge of the cliffs.
The colorful appearance of the guillemot (Uria aalge) egg is due to a maternal genetic ability to manipulate pigments.
Variations in appearance allow the guillemot’s parents to recognize their own egg when they return to crowded rock ledges.

Answer: B – Forest Warbler
This egg belongs to a small bird called the swamp warbler (Acrocephalus palustris), which breeds in Europe and winters in Africa.
The species is a preferred host of the common cuckoo (Cuculus canorus). This means that the warbler’s mother is often tricked into raising the cuckoo’s mother’s chick.
Interestingly, ‘hosts’ of birds such as the swamp warbler, which are victims of such tactics, evolve so that markings on their eggs become more apparent, allowing the host mother to tell the difference between their own brood and the intruder.
But this in turn has caused the so-called ‘parasitic’ mother to evolve to further mimic the appearance of the host eggs – creating an ‘evolutionary arms race’.
