Birdfinding.info ⇒  Common and conspicuous in the core of its range, especially in the chaco and brushlands of Rio Grande do Sul, Uruguay and northeastern Argentina.  In Buenos Aires it can always be found at the Costanera Sur Ecological Reserve.  In Hawaii it is common to abundant throughout Kauai, Oahu, Molokai, Lanai, and Maui.

Red-crested Cardinal

Paroaria coronata

South-central South America; introduced to Hawaii.

Inhabits chaco and other brushy woodlands and savannas of Bolivia, Brazil, Paraguay, Uruguay, and Argentina.  From central Beni, southern Mato Grosso, and western Paraná south to northern Neuquén and southern Buenos Aires Province.

There are apparently introduced populations around several South American cities, including Curitiba, Quito, Lima, Puerto Madryn, São Paulo, and Trelew.

Introduced populations are well established on all the main islands Hawaii, except the Big Island—where the introduced Yellow-billed Cardinal replaces it, although a few wanderers from Maui appear from time to time.

Additional introduced populations were tenuously established on Honshu and Puerto Rico, but have vanished.

Identification

A typical Paroaria cardinal, with slaty-gray upperparts, snow-white underparts, glowing ruby-red head, crest, and bib, and nearly complete white collar.  Named for its most diagnostic feature: a tall, peaked crest which differentiates it from similar species.

The bill is mostly pale, whitish-gray, with a dark-gray ridge and tip, and the legs are dark-gray.

Voice.  Songs are leisurely, variable series of clear, rising and falling whistles, usually about two to four in a given series, which is repeated several times before changing to a new series: Sometimes the whistles are more nasal or wheezy, reminiscent of some vireos:Sometimes nasal or wheezy whistles transition into chatter:Or sometimes one individual’s song transitions into a chattering duet:Typical calls are wheezy or squeaky chirps and chatter:

Cf. Red-cowled Cardinal.  Red-crested and Red-cowled Cardinals are closely related and very similar in plumage.  They usually would not overlap geographically, but introductions have brought them together in southeastern Brazil.

The main differences are that Red-crested has a tall, peaked crest and mostly uniform gray upperparts, whereas Red-cowled has a low, rounded crest and mixed gray and black upperparts.  Red-cowled also has a somewhat thicker bill that is almost perfectly bicolored (all-dark upper mandible and all-pale lower), whereas Red-crested’s bill is mostly pale with a dark ridge.

Notes

Monotypic species.
