The Black-and-White Warbler Mniotilta varia is a fairly common winter resident on Abaco. They are the only birds of the genus Mniotilta (“moss-picker” gr.). Unlike most warblers these birds behave rather like nuthatches, creeping along the trunks and branches of trees grubbing insects out of the bark. Pine trees are ideal for this. A lot of the 37 species of warbler on Abaco are small and yellow. But as soon as I saw one of these for the first time, I was very relieved. I knew exactly what it was – the bird that has been described as ‘a flying humbug’.
Finally, this is a great short video of this little bird in action. Even if you only watch the first 30 seconds, you will be enchanted…

Coots and gallinules (moorhens) tend to get overlooked as birds of interest, being familiar to all and far from unusual in many locations. However, it is hard to imagine a more dramatic waterfowl image than this coot on the point of lift-off. Gerlinde Taurer, a significant contributor to BIRDS OF ABACO, captured this moment – a split second with the bird’s wings raised and the frantic paddle as the bird takes off.
A humorous conversation

WHAT DO LAUGHING GULLS SOUND LIKE? ARE YOU OVERSENSITIVE?
I made a couple of short recordings of the gulls in full humour mode; also a short video of the breeding pair above. If you have never heard them before, you might want to listen to the full 30 seconds. For anyone else there’s a convenient lull at around 15 secs before they kick off again.

The Tricolored Heron Egretta tricolor is one of 6 heron species found on Abaco, and is a permanent breeding resident. To which can be added 4 sorts of egret to complete a line up of expert fishers, all equally at home hunting in the water or from the shore, or surveying the scene from nearby vantage points like bushes and trees. A long neck, a long bill and long legs make this heron species ideally adapted for wading. Like other herons and egrets, it will stand stock-still waiting for the perfect fish to swim into range. However they are also active hunters, and will stalk prey or chase it by striding quickly through the water in pursuit. They eat fish, crustaceans, reptiles, and insects.

Abaco has two permanently resident woodpecker species, the WEST INDIAN WOODPECKER and the HAIRY WOODPECKER. There is a third, migratory woodpecker species that is a fairly common winter resident, the yellow-bellied sapsucker Sphyrapicus varius.
Like its woodpecker cousins, the sapsucker drills holes in trees (see below). The dual purpose is to release the sap, which it eats, and to attract insects that it also eats. A two-course meal, if you like. They’ll also eat insects on an undrilled tree, and even ‘hawk’ for them in flight. They balance their diet with fruit and berries.
The distinctive patterns of sapsucker holes may completely encircle the trunk of a tree with almost mathematical precision. This is sometimes described as ‘girdling’ and may have a damaging effect on a tree, sometimes even killing it if the bark is severely harmed. This may require preventive measures in orchards for example, though note that in the US Yellow-bellied Sapsuckers are listed and protected under the Migratory Bird Treaty Act so radical action is prohibited.

On Abaco, palms are a favourite tree for the sapsuckers. There are several palms along the beach at Delphi. Below is a coconut palm that had seen plenty of sapsucker action, with the drill holes girdling the entire trunk from top to bottom.
In their breeding grounds yellow-bellied sapsuckers excavate a large cavity in a softwood tree as a nest. They mate for life, and often return to the same nest year every year, with the pair sharing nesting duties. I have no idea whether the pair migrate south for the winter together, or whether they agree to take a break from each other. I’d like to think it’s the former…
