List of and Notes on the Birds of the Iles Des Saintes, French West Indies LIST OF AND NOTES ON THE BIRDS OF THE ILES DES SAINTES, FRENCH WEST INDIES CHARLES VAURIE LES Saintes,a small archipelagothat lies south of Guadeloupe,has seldolnbeen visited by ornithologists.No list of its birdsseems to have beenpublished, although, to besure, 25 specieshave been mentioned froin theseislands by Noble (1916), Bond (1936, 1956), Danforth(1939), or Pinchonand Bon Saint-Come(1951). Three of thesewere recorded on doubtfulevidence and, pendingconfirmation, should be deletedfrom the list. Nineteen of the remaining 22 and an additional five were observedby me on 2-5 July 1960,when Mrs. Vaurie and I visitedthe FrenchWest Indiesfor the AmericanMuseum of Natural History. The speciesmentioned by Noble and Danforth were incorporatedin their reportson the birdsof Guadeloupe,those cited by Bondor Pinchonand Bon Saint-Comein generalworks on the birds of the West Indies. The birds reportedso far are listedbelow with a few notes. I aln grateful to James Bond for his very helpful advice, Eugene Eisenmannfor readingthe manuscript,and to the Gendarmerieof Basse Terre and Terre-de-haut for arranging our visit as there is no hotel in Les Saintes. Les Saintesare of volcanicorigin and are separatedfrom the Basse Terre in Guadeloupeby a stormychannel seven miles wide. They con- sist of two relativelylarge islandscalled Terre-de-bas and Terre-de-haut, the only islandsinhabited, and of six small islandsor islets, some of which appear to be the sites of sea-bird colonies. One of these, called La Redonde,lies only 300 metersoff Terre-de-hautbut, unfortunately, is quite inaccessibleas it risesperpendicularly out of the sea to a height of 46 metersand is poundedby huge waves that rise to nearly half its height. The top of La Redonde,which is about 170 meterswide, is alive all day with many seabirds. The other islets,which are probablyoccu- pied by birds also, are slightly lower than La Redondebut similar to it in structure. Terre-de-haut,the only island we visited, is five kilometerslong and variesfrom three quartersof a kilometerto two kilometersin width. The centralpart of the islandis relatively flat, and its coastlineis formed by two magnificentbeaches about one kilometer long. The beachon the lee of the island is quiet, lined by the street of the village and coconut trees;the oneto the windwardis very broad,backed by dunes,and swept by greatrollers. The islandof Dominica,16 milesaway, is clearlyvisible from it. Two large, shallow,brackish ponds are found on this part of 57 58 V^um•:, Birds of lies des 3'aintcs [ Auk [Vol. 78 the island,and one of theseis surroundedby extensiveflats that probably receiveshore birds and perhapsducks during the migration;but, so far, the only migrantnoted for Les Saintesis the Oven-bird(Seiurus auro- capillus). There are also several small, artificial ponds for watering cattle. The rest of Terre-de-hautis ruggedand formed by a seriesof trans- verse hills separatedby narrow, deep valleys, and the coastline,except at the westernend of the island,is very deeplyindented by numerous bays and coves. This western end is formed by a double-headedhill, called Le Chaineau,which rises to 309 meters (over 1,000 feet) and drops into the valley by a seriesof cliffs or steepslopes. These cliffs are the homeof a colonyof the Antillean Martin (Pro•7nedominicensis) and of one pair of American Kestrels (Falco sparverius). Le Chameau and the hill facing it acrossthe valley are heavilywooded, many of the trees being large but giving way on the lower slopesto densescrub consistingchiefly of mesquite. The floor of the valley is given over to pasture,one or two small gardens,and grovesof mangos,citrus, or other leafy trees. The westernend of Terre-de-hautis the least disturbedand supports a good bird life. Some species,such as the hawk, pigeon,two of the doves,flycatcher, bullfinch, and PlumbeousWarbler, were seenonly there. On the rest of the islandthe vegetationbecomes more meager and the birds fewer. The many large iguanas(It7uana delicatissma), whichare foundin its valley,add much to its charmand interest.They are not molestedand sun themselvesor stroll about unconcernedly.A snake,endemic to Les Saintes,is foundthere also but wasnot seenby us. Terre-de-hautis very beautifuland interesting. It has preservedits fauna, sincethe mongoose,which has causedso much destructionin the rest of the West Indies, has never beenintroduced, and as its inhabitants haveshown little interestin exploitingthe island. The peopleare all descendants of Breton seamen and fisherfolk to whom the sea is home and living,although some older men make a desultoryeffort at cultiva- tion and keep a few cows,sheep, and goats. Terre-de-basis muchmore regular in shapeand uniform in its topog- raphy thornis Terre-de-haut. It is squarish,measuring about three kilometers on a side, and rises to 293 meters. It is said to be more woodedthan Terre-de-haut, a fact attestedto by the mapof vegetation. Our visitcoincided with a periodof greatactivity on the part of the birdsand insects,as the rainshad startedonly about two weeksbefore, afterfive months of drought.Some birds were very vocal, and I observed chasing,suggesting territorial activity, although,no doubt,some had Auk 1 V^umE, Birds of lles des Saintes 59 Vol. 78 1 started to nest earlier as Bond writes to me that "The height of the breedingseason in the LesserAntilles is in May, and many birds nest there in April." In the list below, I have onfitted three birds that were included by Danforth (1939) becausethey had beenmentioned from Les Saintesby Noble (1916). These are: Sula leucogaster(Brown Booby), S. sula (Red-footed Booby), and Thalasseusmaximus (Royal Tern). But Noble did not collector see thesebirds, stating that they had been re- ported to him by fishermen. Danforth questionedthe validity of two of these records,and it seemssignificant that Noble omitted all three birds from his list, •nentioningthem merely (with reservation)in the introductionto his paper. Danforthvisited Terre-de-haut on the afternoonof 5 July 1937,spend- ing most of the morning on Terre-de-bas,or on the stoneday and month we visited Terre-de-haut. I have, therefore,quoted his observations when they differ from mine to someextent, and have also mentionedhis records for Terre-de-bas, as all the records from that island in the litera- ture, with the exceptionof Crotophagaani, are to be foundin his paper.

Falco sparverius,American Kestrel. Two pairs in the valley at the westernend of the island. This valley is divided in the middle by a small ridge, which consti- tutes apparently the limit of the territories as the birds were not seen to cross it. One pair had youngand was seencarrying food to the nest,the prey consistingon all occasionsof lizards. The nest was in leafy trees at the base of the cliff, or perhapsOn the cliff that was difficult of approach.

Introduction It well known that Anegada has globally important biodiversity. Indeed, biodiversity is the basis for most livelihoods; supporting fisheries and leading to the attractiveness that is such a draw to visitors. Over the last three years (2003-2006), a project was undertaken on Anegada with a wide range of activities focussing towards this Biodiversity Action Plan. From the outset it was known that the island hosts a globally important coral reef system, regionally significant populations of marine turtles, is of regional importance to birds and supports globally important endemic plants. The project arose following the encouragement of Anegada community members and subsequent extensive consultation between Dr. Godley (University of Exeter) and heads of BVI Conservation and Fisheries Department (CFD) and BVI National Parks Trust (NPT) who requested that funding be sourced for a project which: 1. Allowed the coastal biodiversity of Anegada to be assessed; 2.

SCHUCHMANN-WEGERT Since 1975 we have been studying the population dynamics, foraging strate- gies and reproduction biology of hummingbirds living on several islands in the Lesser Antilles, West Indies. Here, we summarize our observations made on Guadeloupe (Riflet), Dominica (Freshwater Lake, Morne Trois Pitons) and on St. Lucia (Edmond Forest Reserve, Mt. Gimie) of the displays and mounting be- haviour of the Purple-throated Carib Hummingbird {Eulampis jugularis), the largest species in the guild of Lesser Antillean trochilids (average body mass: 8.7 g, n = 19). Behavioral observations were also made on captive Eulampis jug- ularis kept in Bonn. Although some details on the displays and nesting habits of this species have been described (Bond 1941, Schuchmann 1977, Wolf 1975, Wolf & Wolf 1971) we will augment this published information and present some ideas on the adaptiveness of certain behaviours.

These include the globally cays and rocks, with a total land area of approximately 58 threatened Cordia rupicola (CR), Maytenus cymosa (EN) and square miles (150 square km). This archipelago is located Acacia anegadensis (CR). on the Puerto Rican Bank in the north-east Caribbean at A quarter of the 24 reptiles and amphibians identified are approximately 18˚N and 64˚W. The islands once formed a endemic, including the Anegada Rock Iguana Cyclura continuous land mass with the US Virgin Islands and pinguis (CR), which is now restricted to Anegada.

  • The Environment Determines Caribbean Hummingbirds' Vulnerability 22 March 2018
    The environment determines Caribbean hummingbirds' vulnerability 22 March 2018 the scientific journal Proceedings of the Royal Society B. Hummingbird's body size and bill length are often used to predict how specialized and vulnerable the birds are to extinction of the flowers they feed on. However, a new study shows that vulnerability and specialisation of Caribbean hummingbirds are determined by their environment. The study is published in Proceedings of the Royal Society B. Associate Professor Bo Dalsgaard from Center for Macroecology, Evolution and Climate says, "Our study shows that Caribbean hummingbirds living in rainy mountainous landscapes with cooler temperatures are more specialized and vulnerable to extinction of the flowers they drink nectar from, compared to hummingbirds in the lowlands. We believe our results display a general trend that applies to many other animals and plants throughout the world. Thus, protecting nature in mountain regions is very important, if we want to conserve specialized and vulnerable species, which exist in just one or a few places on Earth." There are around 340 hummingbird species in the world, all native to the Americas. Of those, 14 live on the Caribbean islands and only the Rufous- breasted Hermit (Glaucis hirsutus) is also found on the American mainland.

Scientists have now found that this is not the case for hummingbirds on the Caribbean islands.

We also compiled a list of 101 West Indian plant species with hummingbird-adapted flowers (90 of them endemic) and dated the most species-rich genera or tribes, with together 41 hummingbird-dependent species, namely Cestrum (seven spp.), Charianthus (six spp.), Gesnerieae (75 species, c. 14 of them hummingbird-pollinated), Passiflora (ten species, one return to bat-pollination) and Poitea (five spp.), to relate their ages to those of the bird species. Results imply that hummingbirds colonized the West Indies at least five times, from 6.6 Mya onwards, coming from South and Central America, and that there are five pairs of sister species that originated within the region.

Our treasure wasn’t gold, nor sugar. It was every one of the endemic or the restricted distribution birds. It seemed as if every island offered a unique challenge to finding these treasures. Barbados was the easy task. In Dominica and Martinique we practiced patience. In Guadeloupe we built a successful group dynamic, while St. Lucia and St. Vincent challenged us with trails. Each day offered a unique experience, as if each of the Lesser Antilles had a distinctive personality. We started in British-flavored Barbados. A visit to the Graeme Hall Reserve allowed views of one of the few populations of Little Egret in the Americas. We also saw our first target species, the Barbados Bullfinch, one that’s so common that you can see it wandering around the swimming pool area of the hotel. After a full day sailing north, we made it to Dominica.
