A new-to-my-eyes shorebird to love was seen at a local cove. A pair of Pectoral Sandpipers stayed for a day to refuel on the rich feast of invertebrates found in the wrack of seaweed deposited along the shoreline and as you can see, to get some shut-eye. I had spotted a Yellowlegs and was heading to the shoreline to investigate when I nearly tripped over one of the Pectoral Sandpipers. It was so well camouflaged in the drying seaweed. Only a few feet away was its traveling companion, also equally as difficult to see. They appeared at first glance to be something akin to a shorter legged Yellowlegs but I noticed right away the clean line between its crisply stippled upper chest feathers and bright white lower breast plumage. I knew it was unique to the shorebirds we usually see and had to be something special.
The Sandpipers hungrily burrowed their long bills in the soft sand, coming up with mouthful after mouthful of opaque white invertebrates. This seaweed and sand habitat is extraordinarily rich with small insects. As the seaweed piles up on the beach, the sand washes over and buries it. You may notice when walking the sand underneath your feet feels squishy. That’s because of the seaweed beneath, which also becomes a veritable hot house for insects.
The pair were sooo tired. They frequently dozed off in the midst of foraging and didn’t seem at all deterred by my presence. Perhaps I was the first human they had ever encountered and didn’t know to be frightened. Pectoral Sandpipers have one of the longest migrations known. They may journey from the far southern end of South America, to the high Arctic tundra to nest, quite possibly a nearly 20,000 mile journey. Not only that, but once the polygynous male arrives at the breeding grounds, he will criss cross the Arctic looking for females. From satellite transmitters, biologists know that they may stop and mate at as many as 24 different locations. Pectoral Sandpipers are masters of migration and it was no wonder they were so exhausted.
I returned in the afternoon to find the pair had not moved more than a few feet from where they had been seen in the morning. They were still feeding voraciously and sleeping in-between bouts of foraging.
Pectoral Sandpipers are more likely to be seen in the central part of the country during their autumn migration. Because they are mostly foraging in grassy marshes and wet fields on their typical migratory routes, they, along with several over sandpipers, have gained the nickname ‘grasspipers.’ Pectoral Sandpipers are in the same family as Woodcocks and you can sort of see that in the last clip where the male’s chest feathers are puffed out.
Male Pectoral Sandpipers have a special air sac that lies beneath their breast bone. The air sac fills so that he looks like a feathered balloon and while he flies over the female, he lets out throbbing hoots (and many other extraordinary sounds!).
The wind was still blowing hard when i returned the following morning. Neither were seen and I hoped they had taken advantage of the super strong tailwinds to take them to the next leg of their journey, what seems mighty epic to this wingless human.
