Hi Vermontmark. Not aware of any bird group. My husband and I are from Watertown, MA and live in Cabrera (on our 3rd year). The North coast is very under surveyed since there are just not enough people birding in the area. The birding hotspots have not been well identified. Many seabirds/shorebirds we see up in Eastern US breed up there. Here we get them as visitors during migration and some stay for the northern winter while others move through further down West Indies and into South America (fewer resident gull/ tern/shorebird populations than we see in Eastern US). Rice fields/ flooded fields are an area where many shorebirds are hanging out also. Two days ago had a sighting of 487 Glossy ibises/54 Black-Neck Stilts/Pectoral Sandpipers/Limpkins/Greater and Lesser Yellowlegs to name a few all in a flooded rice field (https://ebird.org/caribbean/checklist/S119729559
). The dense foliage makes detection challenging. Migrant birds are not singing which makes detection harder. In Puerto Plata I have not explored much but an area I found was the Estuario del Rio Yasica (https://ebird.org/caribbean/checklist/S101635922
)which I accessed from the town of Veragua (google Wilson La Boca Restaurant and it will take you to this part of the estuary). It gets busy there but early when there are less people it is very nice for birds. Highly recommend ebird for finding where folks have found birds also just go out and explore.
