Prothonotary Warbler (Protonotaria citrea) lives in wet woodlands across Eastern North America. It feeds on insects and spiders. Its conservation status is Least Concern.
Fascinating facts about the Prothonotary Warbler
- At just 13 cm long and weighing a mean 14.3 g, the prothonotary warbler is about the size of a small sparrow yet sports a bright orange-yellow head that flashes like a sunrise over swamp water. Its short, wide tail shows a two-toned pattern, white at the base and dark at the tip, when seen from below, a handy field mark for birders. These compact dimensions let it dart through dense wet-forest foliage, hunting insects and snails while staying low enough to slip under hanging vines, a lifestyle that hinges on its tiny, agile body.
- Unlike any other eastern warbler, the prothonotary builds its nest inside pre-made cavities, old woodpecker holes, natural hollows, or even man-made milk-carton boxes, making it a true cavity specialist. Males often line several empty cavities with moss before a female selects the best one, then she finishes the nest and lays 3-7 eggs. This reliance on holes, so loss of those habitats directly shrinks the number of available nesting sites and threatens breeding success.
- In Canada the warbler is listed as endangered, with only about 30 breeding individuals estimated in Ontario in 2008, while a protected stronghold in South Carolina's Francis Beidler Forest supports more than 2,000 breeding pairs, the densest known population. This stark contrast shows how a single protected swamp can sustain thousands, yet the species remains vulnerable where suitable wetlands disappear, underscoring the importance of preserving large, contiguous swamp habitats for its survival.
