PRESENTING A LARGE BILL… ANIS ON ABACO

The Smooth-billed Ani (Crotophaga ani) is the third member of the cuckoo family found on Abaco, the others being the MANGROVE CUCKOOand the YELLOW-BILLED CUCKOO. Anis range from Florida and the Bahamas in the north, down through the Caribbean to South America, where they are widespread.

Unlike their shy and retiring cuckoo cousins, anis are extrovert shouty birds that like to hang out in noisy gangs and family groups. They can often be found in low scrub, bickering and squawking, and fluttering around. You’ll probably hear them from some way off, sounding like this:

Anis have advanced social, parenting and chick-rearing skills. They build a communal nest for the group, and all share in egg incubation and chick-feeding duties They may raise up to three broods in a season, which keeps the numbers up. Rather touchingly, the young of earlier broods help to feed more recent chicks.

It follows from this that unlike many other cuckoo species, the ani is not a brood parasite. So the species does not lay its eggs in the nests of other, smaller birds which then unwittingly rear the interloper(s), who in turn push the legitimate hatchlings out of the nest and get all the food and attention.

I have tried to discover why an ani’s beak is as it is, without much success. Very often beak shape relates directly to the feeding habits and preferences of a species, but it is hard to see how a diet consisting mainly of insects and small reptiles such as lizards would account for such a prominently protuberant proboscis. Here is a close-up of the item in question.
On Abaco (and indeed elsewhere) Anis are sometimes known as ‘Cemetery Birds’, no doubt because of their all-black appearance (though their raucous tendencies would be quite inappropriate for a graveyard). However although at a distance these birds may look completely black, catch one in the sun at the right angle, and you’ll find that the plumage is far more varied, and with some intricate patterning.

Look for Anis in low scrubland and coppice, cultivated areas, perched in unsteady noisy rows on utility lines, or foraging on the ground.

The appearance and flying abilities of Anis are wonders to behold. As I wrote in The Birds of Abaco, “Their curious heavy beaks, their clumsy flight and their untidy take-off and landing routines suggest a design fault”.

The Philatelic Bureau of the Bahamas Postal Service is commendably committed to featuring the natural history of the Bahamas. Although probably not in the top-ten of anyone’s bird list, the ani nevertheless got its own stamp in a 1991 bird issue.

As far as I know, there is not yet a collective noun for a group of anis. There should be. Any suggestions welcome. Meanwhile I put forward A Commotion of Anis”

  2. I appreciated your extended look at the Ani. I have noticed they seem quite curious and follow me noisily while maintaining a safe perch in a bush as I work around the yard. They love to follow the big mower in the park areas on our Cay and seem to pick up insects that are injured or exposed.
