Black & White Warbler | ROLLING HARBOUR ABACO

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. I remain rather dim about the 37 species of warbler on Abaco. A lot of them 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’.

SUMMER WINTER

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…

BLACK & WHITE WARBLERS (Mniotilta varia)

WINTER VISITORS TO ABACO

By no stretch of the imagination are the images below very impressive. Sorry about that. The wonder is that we noticed this little bird at all – also, that it stayed still for long enough for me to get a bead on it. I credit the sharp eyes of Mrs RH (from whom little is hid) for spotting a fleeting movement on a pine trunk along the Delphi drive. Unlike any other warbler, these small birds feed in the manner of nuthatches or tree / brown creepers. They run rapidly up and down tree trunks and branches foraging on insects in the bark with their sharp little beaks.

The next 2 photos (yes, I agree, they’re not very good, nor taken – the top one, anyway – from an elegant angle) are included to demonstrate the remarkable length and dexterity of the bird’s legs. During the minute we watched it before it flew off, we noted this characteristic legs-splayed ‘pausing pose’ several times.
