During the day, they sleep on the ground or perched, usually lengthwise, on a branch.</p>\n<p>“Nightjars are among the most difficult bird species to study due to their unobtrusive and nocturnal behavior and cryptic plumage,” said lead author Dr. George Sangster and his colleagues.</p>\n<p>In their research, the authors focused on the nightjars of the <a href=\"https://avibase.bsc-eoc.org/species.jsp?avibaseid=04DDADF0515EECDA\" target=\"_blank\" rel=\"noopener\"><em>Caprimulgus macrurus</em> complex</a>.</p>\n<p>This species complex is distributed from Pakistan to Australia and comprises six morphologically similar but vocally distinct species.</p>\n<p>“Fieldwork on Timor and Wetar, Lesser Sunda Islands, has resulted in the discovery of a seventh species in the complex, which we describe as a new species,” the researchers said.</p>\n<p>“This species has previously been confused with <em>Caprimulgus macrurus</em>, <em>Caprimulgus celebensis</em> and <em>Caprimulgus manillensis</em> but it differs from these and all other species in the complex by at least 13 vocal characters.”</p>\n<p>Named <em>Caprimulgus ritae</em>, or the Timor nightjar, the new species is not found in other parts of the range of the <em>Caprimulgus macrurus</em> complex.</p>\n<p>The bird is a forest specialist that has been recorded from a wide range of tropical forests from tall evergreen to highly deciduous dry forest mostly in the lowlands below 1,000 m, with one record from 1,500 m.</p>\n<p>“<em>Caprimulgus ritae</em> is the fourth bird species known to be endemic to both Timor and Wetar,” the scientists said.</p>\n<p>“Other species are the Timor imperial pigeon (<em>Ducula cineracea</em>), the Wetar ground dove (<em>Pampusana gallicolumba hoedtii</em>) and the iris lorikeet (<em>Saudareos iris</em>).”</p>\n<p>“Six additional species on Timor and Wetar are otherwise found only on Atauro, Roti and/or Semau. Hence, the distribution of <em>Caprimulgus ritae</em> is mirrored by that of several other bird species.”</p>\n<p>“Wetar is closer to Timor (51 km) than to Alor (76 km), with the stepping-stone Atauro Island only 23 km off Timor and 21 km off Wetar.”</p>\n<p>“The lack of divergence between the <em>cyt b</em> sequences from Timor and Wetar suggests that colonization of Wetar from Timor, or <em>vice versa</em>, was probably very recent.”</p>\n<p>The <a href=\"https://onlinelibrary.wiley.com/doi/10.1111/ibi.13340\" target=\"_blank\" rel=\"noopener\">study</a> was published in the journal <em>Ibis</em>.</p>\n<p><span>_____</span></p>\n<p><span>Ben F.
