BAHAMA MOCKINGBIRDS ON ABACO

Bahama Mockingbird, Abaco - Tom Sheley

The Bahama Mockingbird Mimus gundlachii is similar to its slightly smaller cousin, the widespread Northern Mockingbird Mimus polyglottis. The range of Bahama Mockingbirds is not restricted to the Bahamas themselves, and includes areas of  Cuba, Jamaica and TCI, so despite the name they are not an endemic species to the Bahamas.  They are also occasional vagrants to the United States, especially – for reasons of proximity – southeastern Florida.

Bahama Mockingbird, Abaco - Peter Mantle

The Bahama Mockingbird is browner than the greyish Northern Mockingbird, and has distinctive streaking and spotting to its breast and undercarriage. This may extend to what you might describe as the bird’s ‘trouser legs’, though I’m sure there’s a more technically correct term.

Bahama Mockingbird, Abaco - Charlie Skinner

Both mockingbird species are found on Abaco. The NMs are ubiquitous in towns, settlements, gardens, coppice and pine forest, whereas BMs are shyer and tend to be found in the pine forest and well away from humans and their operations.

I am astounded by the beauty and variety of their song. It consists of very varied notes and phrases, each repeated 3 or 4 times before moving on to the next sounds in the repertoire. Here is a short 18 second example I recorded, using my unpatented iPhone method, for which see HERE.

For those with interest in birdsong, here is a longer 1:13 minute song from the same bird, with largely different sounds from the first recording made minutes earlier. There’s even a decent stab at imitation of a 1960s Trimphone™. I could have stayed listening for far longer.

An apparently new subspecies, the scarlet-faced mockingbird. In fact the bird had been feeding on red berries, and had managed to collect plenty of the juice round the base of its beak.

Range maps show the stark contrast between the very limited range of the Bahama Mockingbird and the vast distribution of the Northern Mockingbird. An example is below, for comparison.

COMMON GROUND DOVE (‘TOBACCO DOVE’)

Common Ground Dove, Abaco (Tom Reed)

COMMON GROUND DOVE (‘TOBACCO DOVE’)

These small birds Columbina passerina are also known as tobacco doves. Although they sometimes perch in the branches of trees, you are more likely to encounter them on the ground, where they forage for seeds, fruit, and insects.

Common Ground Dove, Abaco 1 (Tom Sheley)

They will often fly in front of a person or vehicle in short fluttering stages, keeping out of reach but never going too far ahead.When they fly, their undersides flash reddish-brown (sometimes described as chestnut) – hence (I presume) the tobacco dove name.

Common Ground Dove, Abaco 2 (Tom Sheley)

The common ground dove is one of the world’s smallest doves – roughly 6 inches long. Its beak has a black tip, and its feathers have a pinkish tinge. The feathers on the head and the breast look rather like scales. Females are similar to males but tend to be greyer.

Common Ground Dove, Abaco (Nina Henry)

Common ground doves mate with their partner for life, and a pair may have 2 or even 3 broods a year. Both parents feed the young birds until they are ready to feed themselves. Rather amazingly, hatchlings can fledge in 11 days. 

Common Ground Dove, Abaco 3 (Nina Henry)

I had embedded a sound file of the dove sound to listen out for. For some glitchy reason it wasn’t working. So a description of the song / call will have to do. It’s a (frankly) rather monotonous and subdued little ‘whoop’.

Common Ground Dove, Abaco 2 (Nina Henry)

My own attempts to photograph a CGD satisfactorily have been rather feeble. I have taken plenty of photos of them on the ground, but nothing memorable, let alone useable. However the one below surprised me by flying onto a branch quite near me, and I had time to squeeze the trigger before it flew off again. Far from perfect compared with others on this page, but I’m not going to let that little detail prevent me from showing it…

GULL-BILLED TERNS

Gull-billed Tern, Abaco (Alex Hughes) 01

GULL-BILLED TERNS ON ABACO

The gull-billed tern Gelochelidon nilotica had a name upgrade from Sterna nilotica some years ago, and was awarded the honour of its own genus. Let’s be clear at the outset: there’s no such thing as a tern-billed gull, which slightly lessens the scope for species confusion. 

Gull-billed Tern, Abaco (Alex Hughes) 04

Gull-billed Tern, Abaco (Alex Hughes) 05

There are 12 species of tern recorded for Abaco. Only one, the royal tern, is a permanent resident. There is one winter resident, the Forster’s tern and there a 6 summer resident terns of varying degrees of commonness. The other four are transient or vagrant, and probably not worth making a special trip to Abaco to find. The GBT is designated SB3, a summer breeding resident that is generally uncommon, though might be more common in particular areas.

The bird gets its name from it short, thick gull-like bill. It’s quite large in tern terms, with a wingspan that may reach 3 foot. They lose their smart black caps in winter.

Gull-billed Tern, Abaco (Alex Hughes) 03

There are 6 species of GBT worldwide, and it is found in every continent. While many terns plunge-dive for fish, the GBT mostly feeds on insects in flight, and will also go after birds eggs and chicks. Small mammals and amphibians are also on the menu.

All photos were taken by Alex Hughes, a contributor to “THE BIRDS OF ABACO”, when he spent some time on Abaco a while back in connection with the conservation of the Abaco Parrot and the preservation of the habitat integrity of their nesting area in the Abaco National Park

BLACK-FACED GRASSQUITS ON ABACO

Black-faced Grassquit male, Abaco (Alex Hughes)

Until 2016 the black-faced grassquit Tiaris bicolor was officially classified with other passerine emberizidae (e.g. antillean bullfinches & sundry New World sparrows).  The classifications committee of the American Ornithological Union recently moved them to join tanager-type species, specifically the dome-nesting ones. Now they are considered to be closely related to Darwin’s finches; and they join the broader category that includes tanagers, grosbeaks, and buntings.

AMERICAN KESTRELS ON ABACO

american-kestrel-f-abaco-bruce-hallett-img_1235-copy

As many or most of the images show, utility wires (also posts) are a favourite perch for kestrels. They get an unimpeded view of the only thing that really matters in their lives – outside the breeding season, of course – PREY. 

american-kestrel-abaco-charles-skinneramerican-kestrel-abaco-2-peter-mantle

In my experience it’s quite rare to see AMKEs on the ground – unless they are in the act of ripping up some hapless rodent pinned to the earth. I was with photographer Tom Sheley when he captured this fine bird in the grass.

TRICOLORED HERONS

TRICOLORED HERON: AN ELEGANT & PATIENT FISHER

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.

THE OSPREY: “ABACO’S GOT TALONS”

Osprey, Abaco (Jim Todd 2)

“ABACO’S GOT TALONS”: THE OSPREY

The magnificent Osprey Pandion haliaetus is one of the world’s most successful raptors and can be found on every continent except Antarctica.

220px-Pandion_haliaetus_global_range.svg

Osprey, Abaco Bahamas (Tom Sheley)

On Abaco the Osprey is a permanent breeding resident, and while certainly not an ‘every day bird’, the chances of seeing one are reasonable. They are fairly often seen flying over the bay at Delphi, or out on the Marls. A pair recently nested at Sandy Point close to Nancy’s restaurant.

Ospreys, Abaco (Jim Todd)

There are few more exhilarating sights in the world of birds than an osprey swooping from a great height into the sea, emerging with a large fish held characteristically ‘fore and aft’ in its talons, and flying into the distance with heavy wing-beats. This wonderful close-up by wildlife photographer PHIL LANOUE shows an osprey that has actually managed to grab dinner for two…

 10 PANDION POINTS TO PONDER

  • Ospreys are also known as sea hawks, fish hawks or fish eagles. They are almost exclusively fish-eating
  • A mature adult’s wingspan may reach 6 feet
  • They are the only members of their taxonomic family, genus and species
  • Ospreys & owls are the only raptors with reversible outer toes to grasp prey firmly
  • They can carry fish weighing more than 4 lbs
  • They dive into water feet first to grab its prey; their nostrils can close up to keep out water
  • Osprey-watch.org is a global site for mapping osprey nest locations / logging nesting observations
  • A New Jersey group has designed the optimum artificial nest platform, now an accepted standard
  • Ospreys usually mate for life
  • Osprey populations in many areas have been affected by pesticides and by egg trophy-hunters

The Osprey is a prolific symbol in national, cultural and sporting themes, and has been depicted on Bahamas stamps. And quite right too.

I think he [Coriolanus] will be to Rome
As is the osprey to the fish, who takes it
By sovereignty of nature…
