The Orchard Oriole (Icterus spurius) is the smallest North American member of the Icteridae family. This diminutive bird boasts a length of 5.9 to 7.1 inches, a modest weight of 0.6 to 1.0 ounces, and a wingspan that stretches to approximately 9.8 inches. The adult male is adorned with a striking chestnut or ochre on the underparts, shoulders, and rump, contrasted by a predominantly black plumage. The female and juvenile counterparts exhibit olive-green upper parts with a yellowish hue gracing their breasts and bellies.
Upon closer inspection, one will notice the pointed and black bill of the Orchard Oriole, with a subtle hint of blue-gray at the base of the lower mandible. White wing bars are a distinctive feature of all adults. It is worth noting that the one-year-old males present a yellow-greenish plumage with a conspicuous black bib, setting them apart from their mature counterparts.
The Orchard Oriole favors semi-open landscapes dotted with deciduous trees. These birds live near lakes and streams, where they construct their nests.
The breeding range of the Orchard Oriole spans eastern North America, from the vicinity of the Canada–United States border down to central Mexico. The subspecies I. s. fuertesi calls the southern regions of Tamaulipas to Veracruz its breeding ground. During the winter months, these birds migrate to a range extending from central Sinaloa and southern Veracruz to northern Colombia and northwestern Venezuela.
Orchard Orioles are nocturnal migrants, embarking on their journeys under the cover of darkness. Their flight is characterized by low swoops, often hugging the ground and seldom rising above the treetops. Courtship is a theatrical display of bowing, seesawing, and begging, accompanied by a high-pitched whistle.
The breeding season sees these birds take to the thorn forests and coastal regions, where they engage in their double breeding endeavors. Their nests tightly woven pouches cradled in the forks of horizontal tree branches and are often clustered in close proximity, fostering a sense of community among the breeding pairs.
The diet of the Orchard Oriole is seasonal. During the breeding season, they feast on insects and spiders. As the seasons turn, they incorporate ripe fruit into their diet, which they process with remarkable efficiency. Winter sees a more varied menu of fruit, nectar, insects, and seeds.
The Orchard Oriole is currently listed as Least Concern on the IUCN Red List, indicating a stable population without immediate threats to its survival.
