First nest of Mangrove Warbler in U. S. with egg

Today with high tide I went into the mangroves by boat and found a nest nearby the other nest. WIthin fifteen feet of the other nest below I found this one with one egg. I took a few shots and backed off and immediately the female came in to the nest. So we should have babies in about two weeks. I think she will lay another egg or two. Dad was busy feeding the first clutch. Sadly some of the nesting material is mono filament and hopefully will not entangle the hatchlings. This nest is lower than the other.
