This page provides answers to the questions posed on the BIRDQUIZ page. The questions are designed to test your knowledge of All the World’s Birds and provide an entertaining way to learn more.

The questions and answers are listed in reverse order of publication, so that the most recent question is at the top. All questions have previously appeared on Twitter as tweets from @charlesrstubbs.

BIRDQUIZ 19/5 In v9.1 of the IOC birdlist, what bird species has the longest (hyphenated) SINGLE WORD English name, with 18 characters? [Hint: it’s well known but infrequently seen.]

339/2466    Chuck-will’s-widow   Antrostomus carolinensis

is a member of the Nightjar family. Resident in s Florida and coastal sc USA, it breeds across eastern North America, wintering in the Caribbean, e Mexico, Central America and the western lowlands of extreme north-west South America. It’s English name is familiar, especially in North America. However, being a nocturnal bird it is seldom seen.

[This bird, along with the All the World’s more than 90 other extant species of Nightjar, is featured in the ATWB Part-by-Part Companion Guide PART FOUR – click here for details.]


BIRDQUIZ 19/4 To have a good chance of seeing both these species on the same day, where would you need to be birding?

636/5797  Ashy Minivet  Pericrocotus divaricatus

680/6142  Island Monarch  Monarcha cinerascens

Answer 19/4:

Island Monarch is resident on coasts and smaller islands of Wallacea in north-west Australasia. Ashy Minivet breeds in eastern Asia, moving south post-breeding to winter in South-east Asia and the Philippines. Additionally, some birds overwinter in the northern part of the island of Sulawesi in north central Indonesia, and it is here that the ranges of these two species overlap. So, to have a good chance of seeing both these species on the same day, you would need to be birding in the coastal region of northern Sulawesi outside of the northern hemisphere breeding season.

BIRDQUIZ 19/3 There’s one species of bird that’s found only in the countries of Jamaica and Colombia.

What is it, and where in Colombia is it regularly present?

Answer 19/3:
