Yellow-fronted Canary

Fairly small gull, common and widespread throughout most of North America. Breeding adults are white-headed with a bold black ring around the bill; nonbreeding adults have smudgy brown markings on the head. Note pale eye and yellow legs. Immatures are mottled brownish overall; note pink bill with black tip. Found along lakes, rivers, ponds, and beaches. More common inland than most other gull species, and quite fond of parking lots and urban areas. Often in flocks. Most similar to Short-billed Gull, but larger and larger-billed. Immatures of the two species are especially difficult to differentiate, but Ring-billed is usually more coarsely mottled.

Medium-sized antbird with a disjunct range from Panama to Brazil. Variable plumage across range. Male generally rufous above and gray below with a white lower belly and blackish face and throat. Females are brown below with dark spotting on the wing coverts. Occurs in pairs in the dense understory of forest edge and second growth; often skulky and difficult to see well. Listen for a rapid trill that starts high and descends in both speed and pitch.

Tiny, disproportionately long-tailed, active, and vocal. The upperparts are gray-brown with heavy dark streaking, the underparts are pale, and each tail feather shows both pale and dark tips. Generally found in rather moist habitats within arid zones, including field margins, riparian woodland, scrub, gardens, and wetlands; can be quite numerous. Very vocal, especially in spring. The song is a long series of dry chirps with a very slight pause between notes, subtly different from the rattling song of Delicate Prinia. Males often sing from obvious perches. Visually extremely similar to Delicate Prinia, but there is little overlap in range. In any areas of overlap, best separated by song, but Graceful is also slightly shorter- and broader-tailed and grayer.
