Message: <blockquote data-quote="DMW" data-source="post: 2415888" data-attributes="member: 80452">Assuming this "redstart" cuckoo has a similar song to Common Cuckoo (otherwise, it would surely have been noticed long ago), it is deeply puzzling that it could be more closely related to Indian Cuckoo.Cuculus species typically have highly distinctive - and apparently persistent -vocalisations. Indian Cuckoo's "one more bottle" song is basically similar across its very wide Asian range, even within resident insular Sundaic populations.I'm struggling to understand why this apparent cryptic species would not either have its own distinct song, or why its song would be similar to Common Cuckoo rather than its closest relative.</blockquote>
