Birds, Turtles and Dead Fish at Silver Sands

Tricolored Heron

The plan was simple, leave home early to do a count at Chancery Lane Swamp for the Caribbean Waterbird Census (CWC), and get back home before 9 am.  Simple!  It was going to plan until I saw a Tricolored Heron (Egretta tricolor) as I drove past the estuary at Silver Rock, Christ Church.  I stopped and the first thing that I noticed was a stench, a really bad stench.  

Dead Fish

As I approached the water I saw the source of the smell, hundreds of dead fish were lining the bank and sick ones in the water. The water was still full of life, lots of healthy looking fish of all ages, thousands of Cane Toad (Rhinella marina) tadpoles feeding on the dead fish, and even more, toadlets were on the banks of the inlet.  Along with the Tricolor, were five juvenile Laughing Gulls (Leucophaeus atricilla) feeding on the fish,  and a few shorebirds - Semipalmated Plovers (Charadrius semipalmatus), Semipalmated Sandpipers (Calidris pusilla), and Spotted Sandpiper (Actitis macularius), feeding on the banks.  While photographing the heron I noticed a hatchling Green Turtle  (Chelonia mydas) stuck in some of the vegetation around the pond and then I found another and another until I had five of these beauties in my clutch.  I contacted Carla Daniel of the Barbados Sea Turtle Project and within minutes, she was on the scene and finding more hatchlings (you can see her video here ). 

In her search, she came across a dead Semipalmated Sandpiper and too sick Semipalmated Plovers.  The other birds in the area appeared healthy, even the gulls which were feeding on the fish.  Unsure of which government entity was responsible for these bodies of water and the quality of them, I reported our findings to both the Ministry of the Environment and the Coastal Zone Management Unit.

I knew that Cane Toads were toxic but I was unsure about the toxicity of the tadpoles and toadlets.  I found a 2015 paper by The Australian Threatened Species Scientific Committee to the Department of Agriculture, Water and the Environment intitled The biological effects, including lethal toxic ingestion, caused by Cane Toads (Bufo marinus) which stated that  “All stages of the Cane Toad's life cycle: eggs, tadpoles, toadlets, and adult toads, are poisonous”.  Can the dead and sick birds be the result of poison, from ingesting the toadlets and have nothing to do with the fish kill?  I am hoping to find the answer to that question.

I never got to  Chancery Lane Swamp for the CWC count and would try to fit it in sometime during the week. Let's hope no more birds are affected by whatever is going on at the Silver Rock estuary, it would be a tragedy for these long-distance travelers who are already under immense pressure.

The Shorebirds Showed Up: A Successful Caribbean Shorebird Count for World Shorebirds Day

Caribbean shorebirds count in 2020! With growing threats to their habitats, perhaps now more than ever.

Our Caribbean partners went out “shorebirding” in their favorite spots between September 3 and 9, 2020, as part of the Global Shorebird Count. Despite some local challenges, the efforts of Caribbean birders were rewarded. Worldwide, preliminary results show 1,567checklists from 1,303 unique locations where 146 species of shorebirds were recorded. The official 2020 results summary results have not been posted yet but will appear on the World Shorebirds Day website. The Caribbean should be well represented. continue reading ...

Snail Kite - A New Bird Species For Barbados

Juvenile Snail Kite

Barbados has recorded its 273^rd bird species - a Snail Kite (Rostrhamus sociabilis)(Clements Checklist v2019 / Avibase) . The juvenile bird was seen and recorded on video at Bay Street, St. Michael by a resident, who shared the video with local birders.  I visited the area on the 8^th and had no problem locating the bird, which was very tolerant of pedestrian traffic.  What was even more surprising than finding this bird was seeing what it was eating.  As its common name suggested this bird feeds mainly on snails,  an aquatic species of snail called Apple Snails to be exact, a snail not common to our island, if present at all.

The bird was feeding on Blackback Land Crabs (Gecarcinus lateralis) and as the images above shows, was efficiently doing so.

The Snail Kite is a medium-sized hawk about 14 - 19” (36 - 48 cm) in length with a long, broad, and rounded wings which are 39–47” (99–120 cm) in width. It has a long, squared-off tail, synonymous with kites, and a dark tipped very hooked beak.  Females and Juveniles, like this one, shows dark brown upperparts, while it is heavily streaked underneath, with the adult female having more of a white base, a field marking being a super bright supercilium or eye brow, while the juvenile base color is more yellowish.  The legs are mainly yellow.  The male Snail Kite is a striking fellow, dark grey all over, with red eyes, bill base, and legs.

This bird most likely arrived from South America, which is the closest range of these birds to Barbados, but there is also a Caribbean breeding population in Cuba and also one in Florida, USA.

We will continue to monitor and document this bird, another first for Barbados, and give updates on any changes.

Stay safe and enjoy your birding.

The Barbados Birds and Birding Report – August

Chancery Lane Swamp

Rain, rain and more rain – that was the theme for August.  The rainy conditions that broke the drought at the end of July continued into August and it brought many wet areas alive with water and birds. Three places that benefited were the old hunting Impoundment at North Point, St. Lucy, Woodbourne Shorebird Refuge (WSR) in St. Philip, and Chancery Lane Swamp in Christ Church, each hosted a significant bird or birding episode that warranted inclusion in this months report. Let's look at the highlights for August.

Birds and Birding for the Month

In August a whopping 91 checklists were created and forwarded to ebird.org, containing 60 species, and six birds were added to the Barbados 2020 checklist. These were Cliff Swallow (Petrochelidon pyrrhonota),  White-rumped Sandpiper (Calidris fuscicollis),  Pectoral Sandpiper Calidris melanotos, Least Tern (Sternula antillarum), and Yellow-crowned Night-Heron (Nyctanassa violacea). Three reasons for this jump in the number of submitted checklists are: (1)the availability of more areas for birds and birding because of the rains, (2) we are in the midst of the fall migration, so more birds to see, and (3)the island has been included in a conservation project to monitor the number of waterbirds at a few locations across the island, thus more frequent visits to these sites.  The program, which is headed by Birds Caribbean, is called the Caribbean Waterbird Census.   I will tell you more about it in another post. 

A few high counts of migrating birds were seen at various locations across the island

For example:

• Semipalmated Sandpiper (Calidris pusilla), had a high count of 157 birds reported by John Webster at North Point, other significant counts were 152, 104, and 100 at other locations.

  

  Whimbrels @ Chancery Lane

• Whimbrel (Numenius phaeopus) a high of 28 birds at Chancery Lane, also 6 birds at North Point.
• Glossy Ibis (Plegadis falcinellus) sightings of this bird were reported in St. Michael, St. Philip, St. Thomas, and an additional one in the north joining with the one that was there for over a year.
