Zeledon’s Antbird

Zeledon's antbird (Hafferia zeledoni) is a species of bird in subfamily Thamnophilinae of family Thamnophilidae, the "typical antbirds". It is found in Colombia, Costa Rica, Ecuador, Nicaragua, and Panama. == Taxonomy and systematics == Zeledon's antbird has two subspecies, the nominate Hafferia z. zeledoni and H. z. berlepschi. American ornithologist Robert Ridgway described them in 1909 in the same paper as separate species, Myrmeciza zeledoni and M. berlepschi. Both taxa were later treated as subspecies of Myrmeciza immaculata, which was at the time called the immaculate antbird. Beginning in 2012 the immaculate antbird was split into what are now the blue-lored antbird (H. immaculata with two subspecies) and Zeledon's antbird with its two subspecies. A molecular phylogenetic study published in 2013 found that genus Myrmeciza was polyphyletic. In the resulting rearrangement to create monophyletic genera, Zeledon's antbird was moved to the newly erected genus Hafferia. The species' English name and specific epithet commemorate the Costa Rican ornithologist José Cástulo Zeledón. == Description == Zeledon's antbird is 17 to 20 cm (6.7 to 7.9 in) long and weighs about 40 to 56 g (1.4 to 2.0 oz). Both sexes have a wide pale blue ring around their eye and a deep…
