Arctic Tern Egg- First egg of the season!

Good news! The first tern eggs of the season have arrived on Metinic Island. Soon all of the eggs will be laid and the incubation period will start. Terns usually lay from 2-4 eggs one at a time until they are all laid. Because the terns are colonial breeders it is advantageous to them to all lay their eggs around the same time. This reduces the chances of predation through the protection of sheer numbers. We are excited to see the first eggs because this means the busy season is on its way. This past week we put together the three blinds on the island and have begun to record sightings of banded birds.

Because we live on an island there are some things we have to do differently that many people take for granted. We thought it would be interesting to show you how we accomplish some of these everyday tasks. Today we will give you our step-by-step guide on how to clean the dishes with no running water:

Step one- retrieve water from well

Step two- fill pot

Step three- boil water in pot using propane stove

Step four- pour boiling water into two tubs; one for washing and one for rinsing.

Step five- clean the dishes

And then you are done! :)

So long for now,

Sunset during the evening perimeter walk

During our evening perimeter walk today, we spotted the first Common Tern egg of the season!

This little speckled beauty is about the size of a walnut and is amazingly well camouflaged. The creamy base color of the egg matches the minimalistic dry-grass nest perfectly, while the soft-toned speckles help it blend into the shadowy substrate.  Tern eggs are predated by Herring Gulls, Black-backed Gulls, and Laughing Gulls, all of which frequent PMI, so this cryptic camouflage is critical to the survival of the little tern-to-be. Keep checking back for updates, because you know what comes after eggs……… chicks!
