ABACO PARROT CHICKS FOR 2014, TOP POSTS & A DODO…

The dawn of a New Year shimmers just below the horizon, with all its bright promise for the future. It  provides a convenient excuse to peer symbolically into the limestone holes of the remarkable ABACO PARROT to take a peek at some newly hatched eggs and the tiny chicks that will, by next spring, look like the handsome bird at the top of the page…Abaco Parrot Nest 3 Abaco Parrot Nest 4 Abaco Parrot Nest 5

This website is not overly preoccupied with stats, but I have had a quick look to see which posts were the most popular during 2013. Here, for better or worse (I didn’t make the choices…), are the top dozen, introduced by the cutest chick of the year, a Wilson’s plover calling for its mum…Tiny Wilson's Plover for 2014

So! Farewell then 2013. Like the Curate’s egg, you were good in parts – indeed, many parts of you were excellent. Now, like Raphus cucullatus, you will become extinct, leaving remains and memories behind you… Thanks to all loyal followers of this site for sticking with it and its eccentricities (especially the musical digressions). If you wound up here by chance, mistyped g@@gle search or sheer misfortune, cheers… A very Happy New Year to you all!

ABACO PARROTS TO CELEBRATE A MODEST LANDMARK

ABACO PARROTS TO CELEBRATE A MODEST LANDMARK

‘Rolling Harbour: The Blog’ had humble beginnings – a dodgy structure built on foundations formed of an unpromising mix of ignorance and incompetence. Gradually it has come together, to the extent that it has just passed the 125,000 visits mark. Abaco is a small and uncrowded island, so the audience demographic [to use biz-speak] isn’t large. However the wildlife, scenery and lifestyle have turned out to have a wider appeal. 1/8 of a million people (or perhaps 1 crazy punter with repetitive strain injury from checking in unhealthily often) deserve a few of Abaco’s unique parrots in return.

ABACO PARROTS & CHICKS – A 2012 BREEDING SEASON PICTURE GALLERY


ABACO PARROTS & CHICKS

A 2012 BREEDING SEASON PICTURE GALLERY

Time to write some more about Abaco’s most famous bird, the unique ground-nesting Amazon / Cuban parrot sub-species that makes Abaco its home, and breeds in the pine forests of the Abaco National Park in the south of the island. You’ll find lots of information and photos on the dedicated page ABACO PARROTS.

This post covers the 2012 breeding season, and highlights the success of scientist Caroline Stahala and her team in helping to secure the future of these rare endangered birds. The population had shrunk to around 2500 (or fewer) some years ago. More recently it had risen to 3000. An intensive conservation program, including anti-predation measures, has proved effective; and a systematic ringing program has enabled the team to keep a close eye on recovering parrot numbers. Caroline says that the population is now in the region of 4000, confirming an encouraging reversal of a dismal decline towards extinction for these beautiful birds.

ABACO PARROTS IN THE PINE FOREST

The parrots breed only in the pine forest, where they nest in quite deep holes in the limestone rock. This makes the nests and the areas round them vulnerable to predation from feral cats and rodents etc; but conversely it offers protection from the forest fires that would destroy tree nests. 

The holes are often well concealed in the undergrowth and take some searching for…

Both parents are involved in the nesting and later chick care. The female lays 2 – 4 eggs.

The chicks hatch after an incubation period of around 26 days

Some of the nest holes are remarkably deep: the parent parrots clamber up and down the sides

The chicks grow the beginnings of feathers, remaining quite unattractive except to their parents

The parent parrots share feeding and care duties

The chicks / fledglings stage are ringed so they can be identified – see ABACO PARROT CHICKS

By coincidence, as I was producing the post above, Craig Layman at THE ABACO SCIENTIST was also ruminating on the topic of Abaco parrot breeding. He posted the comments below, which raise the very interesting question whether the Abaco parrots, with their increased population, may be starting to breed outside the National park. Caroline can probably answer this (see COMMENTS), but does anyone have any direct evidence to suggest a wider breeding habitat? I guess there would need to be a suitably pitted rock structure for the nests, and an absence of the usual cat- and rat-type predators that one might find nearer human populations.

(Sort of) A Bahama Parrot Study

Posted by laymanc 26 Nov 2012

It isn’t really much of a study, but the only “science” I have been able to do over the last week with the continued turbidity of  nearshore waters.

The Bahama parrot (more information HERE and HERE) is one of the iconic Bahamas animals, and the main factor behind the establishment of the ABACO NATIONAL PARK in southern Abaco.  But my study has been conducted instead from my desk in Little Harbour.  My main finding is simple: the range of the parrot has clearly expanded; it has now been a full calendar in which parrots have been in the area.  Just a few days ago two dozen were squawking around the harbour.  The key will be whether they begin nesting here as well – I havent heard reports of that yet.  But if they do, the expanding nesting range will substantially increase long term viability of the parrot on Abaco.  That ends my first ever Bahama parrot study (I really need more time in the water when I come back).

BAHAMA PARROTS: BAHAMAS NATIONAL TRUST DOCUMENTARY


BNT ABACO / INAGUA PARROT DOCUMENTARY

In August 2011 the Bahamas National Trust published a documentary about the resident Abaco and Inagua populations of this Cuban Parrot subspecies. It features research scientist Caroline Stahala, and contains plenty of information about these birds, their nesting and breeding habits, and the problems they face from predation. In places, some of the devastation caused by the extensive forest fires in March 2011 is still evident (see images in earlier POST). If you want to know more about these attractive (but noisy) birds, the documentary video below covers a great deal in 8 minutes…

THE INTRIGUING PARROTS OF GREAT ABACO ISLAND – PODCAST


A 5 minute PODCAST from ABC Radio’s ‘The Science Show’ featuring Caroline Stahala, research scientist and Abaco Parrot expert, and David Knowles of the Bahamas National Trust, Chief Park Warden for Abaco

The online report is headed by this: Holiday homes and resorts are replacing the forests in which the Bahamian parrot of Great Abaco Island breeds. When Christopher Columbus discovered the beautiful Bahamian islands in 1492, he wrote in his journal ‘the flocks of parrots obscure the sun’. Now the Bahamian parrot is confined to just two islands and they’re a protected species. On Great Abaco Island Bahamian parrots breed in the pine forests of the south and, as Pauline Newman discovered, their nesting behaviour is quite extraordinary”

ABACO PARROTS: NEST CAMERAS AND PREDATOR CONTROL


♦ NEW ABACO PARROT LOGO 

[Note: this post replaces the preliminary, typo-ridden and imageless draft that subscribers may have received, for which I stupidly pressed the 'publish' button rather than 'save draft'... Not the 1st time, either... Sorry] 

Scientist Caroline Stahala has spent 10 years researching the Abaco population of the Bahama parrot. Her aim is to develop understanding of their behaviour so that conservation and management strategies for this rare sub-species can be optimised. Particular protection problems arise because Abaco parrots, uniquely, nest underground. Their main vulnerability is to predation by feral cats, racoons and rodents which kill adults, chicks and fledglings in the nest

Predator monitoring and control programs have been in place for several years, removing surprising numbers of feral cats prior to and during the breeding season. Prevention techniques have been refined as predation data has accumulated. In 2011 for the first time motion-sensitive cameras were used, positioned near the openings of vulnerable active nests (shallow or with large openings), monitored 24/7 with infra-red night-time flash. Constant technical adjustments were needed to determine optimum filming distance and memory card size, and to avoid ‘false triggers’ (eg wind)

A great deal of vital data was collected, particularly at night when predation can’t otherwise be effectively monitored. Feral cats were the most frequent visitors, followed by rodents. No racoons were recorded, so these may be less of a threat than expected. One northern mockingbird (above) was caught on film up to no good. It it seems that the camera flash itself may act as a deterrent, something that bears further study. There is also new evidence that some predators approach a nest and ‘case the joint’ for later use. All this data will make it possible to target predator control preventatively, rather than in the sad aftermath of predation – a great step forward. 

Overall, during the 2011 breeding season none of 55 nests monitored was lost due to predation. In previous years, the attrition rates have been around 25%. The use of cameras avoids any disturbance of the parrots and chicks and provides round-the-clock monitoring. If the cameras / flash are in themselves deterrents, that is a simple method of predation control. The new banding project means that it is now possible to be certain whether same parrot (or pair) is using the same nest cavity each year – and of course individuals can more readily be identified

Finally, Caroline confirms that the parrots weathered Hurricane Irene well.  She was still monitoring the breeding territory then, and when she returned to check active nests after the storm, she found the chicks and fledglings safe in their nest cavities

ABACO PARROT PROJECT: CHICK & FLEDGLING BANDING – AMAZING PHOTOS


CAROLINE STAHALA has provided some truly outstanding photos derived from her scientific research work during the summer into the breeding of Abaco Parrots in the National Park. By their very nature, these pictures of direct human contact with these lovely birds must be exceptionally rare, and I am really grateful to Caroline for allowing me to showcase them in this blog.

ABACO PARROT POST – FLEDGING UPDATE


 Click me! 

CAROLINE STAHALA  has sent a quick update on the progress of the Abaco Parrots and chicks as the breeding season (and the associated project) nears its end. The chicks are growing up fast, and will very soon be fledging. CLICK==>>> HERE to admire their cute appearance in their earlier stages.        Caroline says “they are currently, literally, climbing the walls to make their first flight with their parents”. She hopes to provide some photos – perhaps there may be video – in due course. She hasn’t mentioned problems with feral cats, racoons or other predators, so with luck nest raids and chick losses through predation have been low.
