Bird At Beef Island Pond, British Virgin Islands

I saw this bird at the pond on Beef Island today. As I was taking pictures of the bird, he did not move.  Normally if you get too close to them, they would run or fly away.  But he just stood there.  At one point I thought he was maybe injured or something.  Then when I really got close, he ran away.  BUT I was able to get some great pictures of him.  I just need to find out what type of bird it is.  Night Heron.
