Fortipesavis was a tiny bird that lived about 98 million years ago. It had a very strong and wide fourth toe, which helped it grip onto thin, wobbly branches like a kingfisher. Its foot was so unusual that scientists named it the 'strong-footed bird'.1 2

Makambo ya kosepelisa

Fortipesavis is known only from a partial left foot preserved in amber, which is a piece of fossilized tree resin.1

Its fourth toe was almost twice as wide as its second toe, a feature not seen in any other bird, living or extinct.1 2

The foot of Fortipesavis had thick, padded toes with deep grooves between them, which helped it grip tightly onto branches.2

This bird lived in a mangrove forest environment, where it probably perched on thin, swaying branches while hunting for insects.1 2

The fossil of Fortipesavis was found in a piece of amber that weighs only 2.68 grams and is about the size of a large coin.1

Scientists used micro-CT scanning to study the foot inside the amber without damaging the fossil.1

Ntango bamonaki yango: Fortipesavis was named in 2021 by Alexander Clark and Jingmai O'Connor based on a foot preserved in amber from Myanmar. The fossil was first described in 2019 by Lida Xing and colleagues.1 3
Naino bazali kowelana: Scientists are not sure whether Fortipesavis ate insects or fish, because its foot is similar to both modern kingfishers (which eat fish) and bee-eaters (which eat insects).2
