Harriers are migratory grassland raptors that specialize in hunting in grasslands, moors and swamps. As many of their prey items include agricultural pests such as rodents and locusts, they provide immense service to agriculture. The use of pesticides and the loss of grassland habitats is causing a decline in their numbers today.
The cartoon appears on my Gocomics page. Here's one for the fans of harriers and Clint Eastwood!
