A Field Guides Birding Tours Report

Puerto Rico II 2021

December 4-10, 2021 with Tom Johnson guiding

Field Guides Birding Tours
Our lodging at the edge of El Yunque National Forest looks out across a beautiful valley punctuated by waterfalls—it's a great place to wake up, eat a buffet breakfast, and start the birding day. Photo by guide Tom Johnson.

On this short and sweet island tour, we made a thorough birding loop of Puerto Rico in pursuit of as many of the island's habitats and birds as possible. Starting in San Juan in the island's northeast, we headed west to Rio Abajo and then southwest to La Parguera. We stayed in La Parguera for three nights and used it as our base of exploration of Cabo Rojo, Laguna Cartagena, the Maricao Highlands, and more. From here we carried on east along the southern coast of the island en route to our lodging on the south side of El Yunque National Forest. We looked for a few hummingbirds and other birds before returning to San Juan for our flights home.

On the journey, we found all 17 island endemic bird species and many regional specialties as well, all while based out of comfortable lodges and eating tasty Puerto Rican food.

Particularly noteworthy highlights from this tour included Puerto Rican Parrots, Puerto Rican Nightjar, Puerto Rican Owl, Elfin-woods Warbler, Puerto Rican Tanager, and Antillean Crested Hummingbird. We also found a few rarities for the island in the form of a Franklin's Gull and a Wilson's Phalarope at Cabo Rojo.

Check out the highlights video below for a few memorable moments from the week.

Thanks and good birding!

A common wintering duck - seen at La Parguera and Laguna Cartagena.

NORTHERN SHOVELER (Spatula clypeata)

A male and a female were with other waterfowl at Laguna Cartagena.

This video captures a few of the highlights of our week of birding in Puerto Rico. Video by guide Tom Johnson.

WHITE-CHEEKED PINTAIL (Anas bahamensis)

These attractive dabblers were in residence at Laguna Cartagena—we tallied a max of 10 on one visit.

RING-NECKED DUCK (Aythya collaris)

At least two females were mixed in with Ruddy Ducks and other waterfowl at Laguna Cartagena.

RUDDY DUCK (Oxyura jamaicensis)

Common at Laguna Cartagena.

Podicipedidae (Grebes)

LEAST GREBE (Tachybaptus dominicus)

Two were sneaking around and diving in the marsh at Laguna Cartagena on one visit.

PIED-BILLED GREBE (Podilymbus podiceps)

Three at Laguna Cartagena.

Columbidae (Pigeons and Doves)

ROCK PIGEON (Columba livia) [I]

Common in towns and cities.

SCALY-NAPED PIGEON (Patagioenas squamosa)

AFRICAN COLLARED-DOVE (Streptopelia roseogrisea) [I]

Most of the collared-doves we scrutinized or heard appeared to be either this species or hybrids with Eurasian Collared-Dove. We didn't note any pure-looking or pure-sounding Eurasians on this tour, perhaps because we were busy enjoying the native avifauna! [Lots went down on our lists as African/ Eurasian.]

This male Puerto Rican Nightjar showed off his large white tail spots in the dry forest of the southwestern corner of the island. This is very similar in size and shape to the Whip-poor-wills of the mainland, though the voice is quite different! Photo by group member Kathy Brown.
