The Yellow-shouldered Blackbird is a critically endangered icterid endemic to Puerto Rico, with males being entirely glossy black except for a small, vibrant yellow patch on the shoulder. Its population is severely threatened by habitat loss and brood parasitism.
Where to spot
Endemic to Puerto Rico, primarily restricted to coastal mangroves and dry forests. Small populations exist in other isolated areas.
How to spot
Look for its glossy black plumage with the distinct yellow shoulder patch. It can be found foraging low in mangroves or dry scrub. Listen for its distinctive, often chattering or buzzy calls.
When to spot
Year-round resident. Observing this rare bird requires visiting specific protected areas on Puerto Rico, often during early mornings.

Known locally as 'Mariquita de Puerto Rico,' this species has become a flagship for conservation efforts on the island, primarily due to the severe threat from the Shiny Cowbird.
