For individual travellers who want to explore and discover their own birds, this 4-day rail tour round mainland UK should net around 80 species. The cost of travel and lodging if starting from London could be as little as £110. The itinerary takes in four sites on the way to Scotland any time between April and October.
Outside the main passage season Britain’s only endemic, Scottish crossbill, should be possible. Much easier will be red grouse, an endemic subspecies of willow ptarmigan.
The highlight will be breeding seabirds, for which the country is internationally important.
