This year’s exciting field trips are being planned by our conference partners and local hosts, Para la Naturaleza (PLN) and the Sociedad Ornitológica Puertorriqueña, Inc. (SOPI). We’ve organized field trips in the Metro and North-Central, East, North, South, and West regions of Puerto Rico. Tours are available before, during, and after the conference. Registration for these field trips is separate from conference registration. Times listed include travel times to and from destinations. Transportation and snacks and/or lunch will be provided. The pick-up and drop-off location for most field trips will be in a designated area at the Puerto Rico Convention Center. Proceeds from these trips support the work of Para la Naturaleza and help protect habitats for 83 percent of the avifauna that is native and endemic to Puerto Rico!

Registration for these Field Trips is open only to AOS & BC 2022 Conference registrants. Click on the button below to register. This will take you to a registration page where you can login to the AOS Member Portal to register for available field trips.

6:00 a.m.–12:30 p.m. AST
Location: Northern Karst Region
Cost: TBD

We’ll bird in the Northern Karst region, stopping along the way to look for Puerto Rican endemics plus many Caribbean specialties. Karst, a landscape characterized by eroded limestone, covers more than one third of the Island’s territory. The Northern Karst is located primarily in the subtropical moist forest life zone and originated in a marine environment, as many as 140 million years ago. Geological processes have created spectacular landforms, such as the haystack hills, or mogotes, which are unique formations. Due to its rugged topography the Karst Region of Puerto Rico holds the most extensive forest canopy cover on the Island. The Karst Region also harbors the richest biodiversity in Puerto Rico, with more than 1,300 species of plants and animals found here. It is prime habitat for most of the native and endemic species of wildlife, including 30 federally listed threatened and endangered species. Many of these species are only known from Karst ecosystems. Many of the Neotropical migratory birds use the Karst as wintering habitat. The northern Karst belt of Puerto Rico has also been identified as a viable release site for the establishment of the second wild population of the endangered Puerto Rican Parrot. Some of the forests and reserves we may visit, if needed: Tortuguero Lagoon Natural Reserve, Cambalache State Forest, Caño Tiburones.

The history of Hacienda Buena Vista is linked to the life of the Vives family, their summer residence and what today is the historical site of this natural area. The river and the force of its current are the protagonists of a relationship between nature and agriculture mediated by slavery. Historical buildings and one-of-a-kind machinery remain from this process, along with a sophisticated system of waterworks. Come and join a specialist who will guide you through the rich history of this place. This is our traditional tour, which incorporates a rotating seasonal theme into the interpretation of this natural protected area’s history and nature.

Rio Abajo State Forest is the home of the most successful population of the extremely endangered Puerto Rican Parrot. Because El Yunque National Forest in eastern Puerto Rico’s highlands was the last place the parrots survived in the wild, biologists had long believed the parrots should be reintroduced there. But after years of frustrating attempts to establish a healthy population at El Yunque, they decided to try another site, selecting Rio Abajo, a region of rugged terrain 60 miles to the west. Parrots disappeared from Rio Abajo in the 1920s following the loss of primary forests, but today the area supports dense second-growth woodlands suitable for the birds. In 2006, scientists introduced a new flock to the region, and since then, “the population in Rio Abajo has taken us by surprise,” says Tom White, a U.S. Fish and Wildlife Service biologist with the Puerto Rican Parrot Recovery Program. “We had no idea it would work so well.”

The Rio Abajo flock numbers at as many as 160. At least this past year, around 60 birds have fled from wild nests, a record! Many continue to settle around the aviary cages, creating a flock of captive and wild birds. The sight of wild parrots wheeling through the forest and the sound of their clown-horn squawks stimulate captive birds to lay. A member of the team who works daily with them will show us how they do their excellent job.  

NOTE: Proceeds will be donated to World Parrot Trust.
