The Circle of Life: Jacobin Chicks

Blog post written by Marina Garrido, Sea Turtle Research Field Assistant

Several months ago, while returning to the station after spending a long morning working to build a new hatchery, some volunteers from the University of Costa Rica and I spotted the nest of a white-necked jacobin (Florisuga mellivora) close to the trail. We were very lucky to see the mother incubating her eggs in a nest made of soft vegetation and cobwebs. This delicate nest was on the surface of a large leaf covered and protected by other leaves.

I was fascinated by the discovery, so almost every day after patrolling Piro beach, I would go to check on the nest.

The white-necked jacobin not only feeds on nectar, but on flying insects as well, catching them one by one in shorts flights. The plumage of the male is of beautiful bright colours, which he displays during the breeding season by dancing around the female to show off his attractiveness.

The chicks grew up quite fast, as in just a few weeks they were ready to leave the nest and find their own adventures. One of them left first while the other stayed in the nest for four more days. It is always difficult to leave our comfortable home and make the big jump, however, as it is said: those who do not jump will never fly.
