@Ian that bird in your pic is a Tern, you can see plenty of them in SRP, they are water birds that feed on crustaceans (not sure of the spelling hehe)
@edwin_sn I used to be a member of WBCP but I go inactive now coz I'm busy with work, I was one of the 1st to monitor and lists the migrant birds in SRP, I even saw a rare duck species from Australia called Whistling Duck and I have to wake up 5AM and go to SRP to catch them before they will fly to another location around 5:30AM, wild ducks always fly in V-Formation and it really looks great
I suggest you buy a book about Philippine birds in National Bookstore and it only cost P300 and its full color
