§ Mr. Paterson
To ask the Secretary of State for Environment, Food and Rural Affairs what the estimated population was of(a) corncrakes, (b) woodlarks, (c) nightjars, (d) skylarks, (e) curlews, (f) snipe, (g) redshanks and (h) yellowhammers in Great Britain in 1990; and what the current estimate of the population is. 
§ Mr. Bradshaw
Curlew, snipe and redshank are amber-listed. All the rest are red-listed. Red list species are those that are Globally Threatened according to IUCN criteria; those whose population or range has declined rapidly in recent years; and those that have declined historically and not shown a substantial recent recovery. Amber list species are those with an unfavourable conservation status in Europe, those whose population or range has declined moderately in recent years; those whose population has declined historically but made a substantial recent recovery; rare breeders; and those with internationally important or localised populations. Species that fulfil none of the criteria are green-listed.
The estimation of the various bird populations is given as follows. 514W
