Common Terns Finally Getting Started

So it’s been over a month now that I’ve been watching the terns around Rye Bay and the Sandwich Terns have been the main show so far.  The Little Terns have even been settling down a bit but the Common Terns have taken until this week to get going.  But they are at last, bringing in food and even laying eggs.

You can see the pair here don’t have much of a nest- the two eggs in the top right of the image are in a small scrape with a few small twigs.  This helps with camouflaging the valuable eggs, along with the cryptic patterning on brown and green on the shells.  Tern eggs are very variable and if it wasn’t for the few twigs and attending birds it would be almost impossible to discover the eggs- something they rely on if a predator approaches as they leave the nest to attack and distract any would be egg thieves.

Luckily this doesn’t happen too often as the birds at Rye Harbour nest on small islands set on inland lagoons which are themselves set within electrified fences and monitored by the nature reserve staff.  So hopefully these two eggs will hatch and grow up to breeding age, and might even be joined by a third as the female only laid the second egg this morning!
