Created from Britannica articles using AI. AI can make mistakes, so verify using Britannica articles.

There are eight species of longclaw in the genus Macronyx. These African birds are insect-eaters and are related to pipits. They share similarities in size, shape, and coloration with New World meadowlarks, including streaked brown backs, yellow underparts, a black V on the neck, and white tail feathers. This resemblance is an example of convergence, where unrelated species develop similar adaptations due to similar ecological roles.1
