Day 212: July 30 – Maternal care


Sunny, warm, and calm

        A wonderful morning awaits us on LBI as I get an early start to check on the activity at the beach.  It’s the same cast of characters at first with the Forster’s terns working hard at getting breakfast from the crashing surf.  As the waves hit the shore and run up onto the beach, the terns first hover and then drop down to pick up whatever morsel the sea has delivered.

    

   Eventually, I notice that there are a couple of young birds which have taken up positions on the beach and are quietly awaiting their parents return with a bit of breakfast for them as well.  They remain quiet until “Mom” come near and then the younsters let the parent know that they are hungry and ready for a bit to eat.

       The parent comes in response to the calls of the young and delivers that ort the juvenile bird had so patiently waited for. 





    


    As I watched this scenario play out, it became obvious that pedestrian traffic can really interfere with the normal routine of these birds.  More often than not, as the little birds awaited their delivery,  joggers, strollers, fishermen, kids just doing what kids do and others would come by and spook the juveniles into flight.  The bird would fly away, circle around, land and take up position once again only to be chased off once again by the next passing human.

      I did notice this morning one other tern I had not seen up until now.  A Common tern was mixed in with the Forsters, making me wonder how many others had gone unnoticed.  The two species look so similar that I very easily could have must assumed they were all Forsters and overlooked the Commons.


Common tern (note dark wind-tips)

       As I prepared to head back up to the beach house, a larger bird flew overhead at some distance out to sea.  Even though the bird was far off, the silhouette was unmistakable…..an American oystercatcher. 


       My plan is to head across the island and visit the bay side tomorrow morning to see if I can drum up any new species.  Sure is nice to be back to the sea.
