The grey-headed tanager is a species of neotropical bird found in Central America and Northern South America. This bird prefers moist lowland, subtropical and tropical swamps. They are also found in edge habitat. These birds can be observed quickly darting around the forest in search of fruits and insects. One really amazing hunting strategy these birds use is following swarms of army ants marching along the forest floor and feeding on the insects trying to escape from the ant brigade.
Grey-headed tanagers also can raise up the feathers on their head to appear larger to intimidate any threats. While traveling on a Running Wild Expedition, we met up with the Monteverde Institute and helped conduct some bird surveys with mist nets. We identified, sexed, weighed and measured the birds to collect valuable data to help researchers understand forest ecosystem dynamics and and how it is being affected by climate change as we were right on the border of the Monteverde cloud forest. This ecosystem is delicate and exists within a narrow field of parameters. Climate change is causing this ecosystem to move up in elevation and forever changing the forest composition across Costa Rica.



The Monteverde Institute was started with the purpose of being a public service, non-profit association, dedicated to peace, justice, knowledge and the vision of a sustainable future. It provides programs which promote the appreciation of diversity and community, spirituality and the wellness of all living beings. These opportunities are designed for people from other countries and Costa Rica and for the residents of the Monteverde community and the surrounding zone.
