Here’s a quiz – and it’s just for fun. The answers will be posted at 7pm this evening.
If you have the February issue of British Birds (with a dipper on the cover) you can look up most of the answers in the excellent article on population estimates of birds in the UK.
1. Which bird species has the largest UK breeding population?
2. How many UK breeding bird species have populations of over 1 million pairs?
3. Which is the commonest UK breeding species that Mark Avery has never seen anywhere in the world (UK population of 48,000 pairs)?
4. Which is the commoner in each of these pairs of species: little owl and barn owl; chiffchaff and willow warbler; jackdaw and carrion crow; yellowhammer and reed bunting; red kite and merlin?
5. All these species have similar-sized breeding populations in the UK; woodlark, goosander, Dartford warbler and willow tit. Are they in the 2000s, 3000s, 4000s, 5000s or 6000s?
