Birds of the UPR Botanical Garden

Endemics you can see in one morning

Among the species with the most open records in the garden area, according to GBIF, are Puerto Rican Woodpecker, Puerto Rican Oriole, Puerto Rican Flycatcher, and Puerto Rican Spindalis, all four endemic. The woodpecker gives itself away with a loud call and red breast; the oriole, black and yellow, often works palms and tall trees. The spindalis looks for fruit, and the male is unmistakable with a black-and-white striped head and orange breast.

With fewer records come Puerto Rican Tody, Puerto Rican Owl, and Green Mango. Look for the tody in shaded understory; you will usually hear it before you see it. The owl is nocturnal and the garden closes around dusk, so detecting it is uncommon; do not use lights or playback to attract it.

Lakes, herons, and waterbirds

The UPR lists lakes and waterfalls among the garden's features, which explains why records include waterbirds you might not expect in an urban garden. Green Heron, Great Egret, Common Gallinule, and Least Grebe appear in the GBIF list for the area, along with Yellow-crowned Night Heron and, in winter, Belted Kingfisher.

Least Grebe is small, dark, and dives often; the gallinule has a red frontal shield. Walk the shore slowly and pause before bends: many waterbirds hide in edge vegetation and move off if you walk fast.

Parakeets and introduced birds: identify them carefully

A defining feature of San Juan's birdlife is the number of introduced species. In the garden area, GBIF shows many White-winged Parakeet records, plus Monk Parakeet, Venezuelan Troupial, Orange-cheeked Waxbill, and Bronze Mannikin. There are also records of Blue-and-yellow Macaw, which in Puerto Rico come from escaped or released birds.

Separating native from introduced birds matters for reading what you see. White-winged Parakeet shows a white and yellow wing patch in flight; Monk Parakeet has a gray face and breast. If you see a parakeet you do not recognize, photograph it and note its behavior rather than assuming it is an established species.

Winter migrants and raptors

From October to April the garden's trees host migrant warblers. Northern Parula has the most records in the area, followed by Prairie Warbler, Black-and-white Warbler, and Northern Waterthrush. Look for mixed flocks with Bananaquits: migrants often move with residents.

Overhead, Red-tailed Hawk and American Kestrel are the most frequent in the records, and Peregrine Falcon and Osprey also appear. Black-whiskered Vireo, which winters in South America, shows up in spring and summer. These species give you reasons to return in a different season.

Getting there, hours, and tours

The official address is 1187 Calle Flamboyán, San Juan, and the entrance is on Calle Guaracanal, reached from PR-1 between Río Piedras and Caguas. The highway splits the garden into North and South, and the UPR says most visitor attractions are in the South garden. The federal Forest Service library, specializing in botany, is also on site.

Admission is free. One UPR page lists hours of Monday to Friday, 6:00 a.m. to 6:00 p.m., and another says every day, so confirm before a weekend visit. It closes on days such as New Year's Day, Good Friday, Thanksgiving, and Christmas. Guided tours run Monday to Friday at 9:30 a.m. and 1:00 p.m., with a 10-person minimum and a reservation; the UPR lists $1 per person for walking tours and $5 for the mini-trolley.

What birds can you see at the Río Piedras Botanical Garden?

Open records for the area include endemics such as Puerto Rican Woodpecker, Puerto Rican Oriole, Puerto Rican Spindalis, Puerto Rican Flycatcher, and Puerto Rican Tody. There are also herons, gallinules, and grebes on the lakes, introduced parakeets, and migrant warblers in winter.

What are the UPR Botanical Garden hours?

The UPR lists hours of 6:00 a.m. to 6:00 p.m. One of its pages says Monday to Friday and another says every day, so it is worth calling (787) 758-9957 before a weekend visit.
