Field notes
- It is classified as a 'super-tramp' species due to its exceptional ability to colonize diverse and remote island habitats.
- The species is a notorious nest predator, frequently consuming the eggs and nestlings of other birds, including the endangered Puerto Rican Parrot.
- Unlike most other thrashers, it possesses a striking pearlescent white or pale yellow iris that gives the bird its common name.
- While primarily a cavity nester, it is highly adaptable and will utilize nesting boxes, rock crevices, or even open tree branches.
- Its opportunistic diet ranges from fruits and berries to small vertebrates like lizards, frogs, and even small crabs.
Habitat
Humid montane forests, woodlands, coastal scrub, and suburban gardens.
Range
The Caribbean, ranging from the Bahamas and Puerto Rico through the Lesser Antilles to islands off the Venezuelan coast.
