The following information is from a correspondent who took a family holiday to Réunion in July 2005. The sightings are not of uncommon species but they include several endemic and near endemic species and as this is the first news we have received from this island, we felt that it should be included.

The following species were each observed on several days of the holiday: White-tailed Tropicbird Phaethon lepturus; Madagascar (Réunion) Marsh Harrier Circus maillardi; Madagascar Turtle Dove Streptopelia picturata; Mascarene Swiftlet Aerodramus francicus; Mascarene Martin Phedina borbonica; Réunion Stonechat Saxicola tectes; Réunion White-eye Zosterops olivaceus; Mascarene Grey White-eye Z. borbonicus and Madagascar Red Fody Foudia madagascariensis.

The following species introduced to Réunion were also seen on several days: Zebra Dove Geopelia striata; Red-whiskered Bulbul Pycnonotus jocosus; Common Myna Acridotheres tristis; House Sparrow Passer domesticus; Village Weaver Ploceus cucullatus and Common Waxbill Estrilda astrild.

In addition, species that were seen less frequently were Green-backed Heron Butorides striata, Madagascar Partridge Margaroperdix madagascariensis, Madagascar Buttonquail Turnix nigricollis, Subantarctic Skua Catharacta antarctica lonnbergi, Brown Noddy Anous stolidus, Olivaceous (Réunion) Bulbul Hypsipetes borbonicus and Mascarene Paradise Flycatcher Terpsiphone bourbonnensis.

Conservation

Thu, 01/24/2013 - 11:24 -- abc_admin

Since their permanent establishment in 1646, human colonists have brought about the loss of 75% of the native vegetation area (around 650 km2 remain) and 50% of the native vertebrate fauna including 55% of the birds. In addition, numerous species have been introduced of which 592 plants, 8 mammal, 20 bird and 12 reptile species have become naturalised. Native species and ecosystems are threatened by exotic species invasion and once established, active management is required if conservation is to be achieved.

There are four direct human threats to bird populations: illegal hunting; opening of new paths and tracks into forest areas; fire in the drier areas; and the disorientation of seabirds when taking their first flights, caused by artificial lights. A programme to rescue disoriented birds especially Barau’s Petrel Pterodroma baraui (500 birds in 1998) is carried out each year.

Several existing and proposed categories of protected area exist: Nature Reserve; Protected Biotope; State Biological Reserve; Other reserves; and Reserves to be established. Four of the Iles Eparses became Nature Reserves in 1975 although these designations have not been approved nationally. France has signed and ratified a large number of international environmental treaties.

Conservation News

20th September 2006: Implementation of the Réunion Cuckoo-Shrike Coracina newtoni action plan is producing rapid results.

Control of predatory rats and cats is a key recommendation of the plan, and already in Réserve Naturelle de La Roche Ecrite in northern La Réunion (Indian Ocean) it has led to four out of five pairs of Cuckoo-Shrike successfully rearing chicks, compared to just two out of six pairs raising young at a nearby site without control.

Although the population of Réunion Cuckoo-Shrike remained fairly constant at around 120 pairs between the 1970s and the 1990s, it has been declining over the last decade. Currently males outnumber females by almost two to one, and the remaining population is estimated at fewer than 50 pairs and the species is classified as Endangered. It is thought birds once primarily occupied lowland forest, but under the pressures of habitat loss and degradation, forest fires and predation by alien invasives, this species has retreated to a 16 km² patch of mountainous rainforest in the north of the island.

Visiting

Birding tours

Birdquest and Rockjumper operate tours to Réunion.

Guides

Birdwatchers on holiday in La Réunion can contact SEOR by post (see contact page for details). They can participate in a birdwatching day (the programme is on the SEOR web site), or if it is convenient for SEOR, it may be possible to carry out field work with permanent staff.

Trip reports

A birder's guide to Mauritius and Réunion (with seabirds of the western Indian Ocean) (1993) by Sargeant, D. published privately. This a 14 page report based on a cruise from Durban. The report includes an itinerary, site guide and checklists.

Reunion trip report covers a combined wildlife and tourism trip to Réunion and Mauritius in July 1999 by Gerard Joannes.

Logistics

One can fly to Réunion from Mauritius, the Seychelles, Comoros, Mayotte, Madagascar, South Africa, Kenya and France. The flights from France are generally more expensive between July and mid-September and at around Christmas time. There's currently no departure tax. Roland Garros Airport is located about 11 km east of St-Denis; an airport bus travels frequently between the airport and St-Denis, as do taxis.

The road system on the island is excellent and well signposted, and heading into the mountains via the cirque roads is a magnificent experience. As in the rest of France, Réunion drives on the right. To drive on the island, you must have either a valid French or international driver's licence.

Safety

Guidebooks, travel companies and websites provide much of the advice one needs, but key points warrant repetition here: (1) although there is no malaria in Réunion, you should be aware of the general risk especially if you are travelling to or from countries with malaria carrying mosquitoes (2) always ensure you have sufficient water and some method of purification (even if this comprises a pot and a campfire for boiling); (3) do not underestimate the danger of being in the sun for too long, ensure you use sun-block, drink plenty of water and wear a hat; (4) although the prevalence of AIDS is very low, be aware of the general risk of AIDS; (5) ensure that you take a reasonably-equipped first-aid pack with you including supplies of hypodermic and suturing needles. See the following website or your local embassy website for the latest safety and travel information: UK Foreign and Commonwealth Office.

Hotspots

The following extracts are taken from "Southern African Birdfinder: where to find 1,500 birds in the southern third of Africa and Madagascar" by Callan Cohen, Claire Spottiswoode and Jonathan Rossouw, to be released by Struik Publishers in 2006. Please visit www.sabirdfinder.com or contact callan@birdingafrica.com for more information.

All of Réunion’s land bird endemics can be conveniently found at just one site, La Roche Ecrite, a thirty-minute drive from St Denis. A hiking trail leading into the mountainous interior begins here, and the first three kilometres are best for birding. Réunion Stonechat Saxicola tectes, Olivaceous Bulbul Hypsipetes borbonicus, Réunion White-eye Zosterops olivaceus are relatively easy to find here and Mascarene Paradise-Flycatcher Terpsiphone bourbonnensis is easier here than on Mauritius. Réunion Cuckoo-Shrike Coracina newtoni can be more tricky and is best found in the vicinity of the three kilometre mark. Mascarene Grey White-eye Zosterops borbonicus can also be seen.

Barau’s Pterodroma baraui and Mascarene Black Petrel Pterodroma aterrima are best seen by chartering a deep-sea fishing vessel from either St Giles or St Pierre; the birds are best seen between 10 and 20 km from shore in the last few hours before sunset.

Important Bird Areas

Thu, 01/24/2013 - 11:15 -- abc_admin

La Réunion supports 4 endemic land bird species of which one is threatened. In addition, 3 landbird species are shared only with Mauritius. All seven of these species are restricted range which defines the Réunion Endemic Bird Area (EBA). Additionally, there are 3 further species of conservation concern of which 2 are petrel species plus Madagascar Marsh Harrier Circus maillardi which is shared with Madagascar and the Comores.

Iles Eparses support large populations of boobies, tropicbirds, frigatebirds and terns.

There are 12 Important Bird Areas (IBAs) in total of which 8 are in La Réunion island itself and cover 216 km2 or 9% of the land surface and the remaining 4 of Iles Eparses cover around 40 km2 or 89% of the land surface. The site names and the administrative regions of the 12 IBAs are as follows:

Piton des Neiges—Gros Morne Salazie, Saint-Louis
Grand Bénard—Tapcal Saint-Louis, Saint-Paul
Plaine des Chicots—Plaine d’Affouches Saint-Denis
