Río Abajo State Forest, Puerto Rico

Rugged limestone terrain and a sheltered inland location protect Río Abajo State Forest from hurricanes and encroaching development, making it an effective refuge for the critically endangered Puerto Rican Parrot.  The only currently viable population of that species lives in the heart of Río Abajo.  The largely intact wet tropical forest at this site also supports several other endemic birds, including Puerto Rican Owl and the endangered Puerto Rican form of Broad-winged Hawk.

Orientation

Directions

Río Abajo is a 10-minute drive from one of Puerto Rico’s major interior highways, PR-10.  The most direct access to the area of interest in the forest is via PR-6612, which intersects PR-10 inconspicuously about 18 km south of Arecibo, or 7 km north of Utuado.

Turn north onto PR-6612 and you will quickly reach a T-junction with PR-621.  Turn left here and go 4 km through a backwoods neighborhood until you reach a yellow gate, which is the entry point into the state forest.

Attractions

The famous Arecibo Observatory and Cavernas del Río Camuy National Park are a short distance west of Río Abajo State Forest.  Access to these attractions is via Arecibo.

Birdfinding

Puerto Rican Parrot Breeding Facility.  Finding the Puerto Rican Parrot is the main objective of most visits to Río Abajo.  Success is not guaranteed, but it is likely.  Much of the wild-living population—which consists of released birds and their wild-hatched progeny—apparently remains sentimentally attached to the captive-breeding facility, the José L. Vivaldi Memorial Aviary, and they continue to roost nearby.

To reach the facility, park beside the yellow entrance gate, and walk the road for about 2 km to the gate of the breeding facility.  Free-flying parrots are most reliably present early in the morning and late in the afternoon, but they can often be heard and seen in the treetops around the facility at any time of day.

To explore the area further, backtrack a short distance from the facility gate and look for a wide gravel trail on your right (i.e., on your left as you arrive).  This trail takes a wide loop through the forest around the breeding facility.  Keep to the right at each fork in the trail, and at the second powerline cut follow the small side trail to the right under the powerlines to the steel pylon (18°19’59.8” N / 66°43’10.3” W).  From this vantage point, overlooking the powerline cut toward the facility, you will have a view of the area where the parrots fly to and from their roosts.

“Puerto Rican Broad-winged Hawk” can often be seen along the trail.  Río Abajo and the surrounding hills apparently support most of the remaining population of this distinctive endangered subspecies.

Río Abajo is also one of the most reliable sites for Puerto Rican Owl.  The most efficient way to find one is to arrive an hour or two before dawn and listen for them while walking along the road to the parrot breeding facility.  There will often be several calling, and usually at least one will be close to the road.

It is also possible to find the owl by visiting in late afternoon and waiting into the evening to search for them.  This approach is likely to take longer, waiting through dusk until the owls to begin calling.

Accommodations

The nearest accommodations and restaurants are in Utuado.  For greater variety, Arecibo is the closest city.

TJ Ranch.  A rural guesthouse near Río Abajo has become a popular lodging option for birdwatchers.  The habitat is more open than in the state forest, but it supports most of the same species.  There are no Puerto Rican Parrots at the ranch, but it is a good site for “Puerto Rican Broad-winged Hawk,” Puerto Rican Screech-Owl, and several other endemics: the emerald, the tody, the kingbird, the bullfinch, the oriole, and the euphonia.

TJ Ranch is private property, not open on demand to the public at large.  Its website clearly states that visitors must make advance reservations (confirmed by phone) to enter the property.  Therefore, do not attempt to visit unless you have spoken to the owners.

TJ Ranch is about 25 minutes’ drive east of Río Abajo, nestled among scenic haystack hills that are part of the same geological formation as the state forest.  The route to TJ Ranch crosses the Dos Bocas Dam, a local landmark.  Immediately after the dam, turn left (uphill), then at the top of the hill turn right and continue 3.5 km to TJ Ranch.

Notes

When to Visit

As with other forested sites in Puerto Rico, the best time to visit is approximately February through May, when the endemics are most vocal and conspicuous.
