When we moved to Valsad from Patan, lockdown due to Covid-19 was already imposed by the government of India. During the lockdown we were not able to go outside, so we enjoyed window birding from our residence. When the Government of India started unlocking, we started birding at local places. At Patan we heard about Dharasana Wetland. Dharasana is very near to our home so we went for birding there whenever we have time. There are countless Zinga-farms (Prawn farming) situated around Dharasana. During monsoon these farms are not doing Zinga-farming. When farms are inactive, lots of birds like Terns attracted here for fishing. One lucky day we got our biggest lifer - Bridle Tern at such a farm.
On that day we observed many Tern flying over the one of the inactive Zinga-farm. Generally River Tern, Gull-billed Tern, Caspian Tern are seen in our area, but one Tern among these flying birds looks different in colour – dark upper part and dark wings. When we notice a difference, we focus our photography on that particular bird. We assumed it as a juvenile bird of some Tern species. After coming back to the home, going through the field guide we get to know that it was a Bridle Tern. Big lifer for us as these terns are mostly pelagic, rarely visits shore. In the same place we also find our second lifer Common Tern.
Tropical tern with gray back, black cap, and white forehead. Very rarely seen near land except when blown off course by a hurricane. Frequently perches on floating wood or other debris far offshore. Most similar to Sooty Tern but paler gray above with more extensive white tail edges and paler undersides of flight feathers. Young birds show whitish head with pale barring on wings and back.
