Santa Maria e Fomigas/l990: ReIatdrio (87-91) SOME STUDIES OF CORY'S SHEAR WATER Calonectris diomeden, AROUND THE ISLAND OF SANTA MARIA LESLIE BATTY Unidade de CiCncias e Tecnologias dos Recursos Aquaticos Universidade do Algarve. Campo de Gambelas P-8000 F A R 0  Preliminary observations were made in relation to preparation for a joint University of Glasgow/Universidade do Algarve expedition to the Azores, in Augustfseptember, 1990, to study the diet, feeding ecology and colony attendance patterns of the Cagarro or Cory's shearwater Caloneclris diomedea.  A search was made for breeding colonies suitable for detailed studies, and observations were made on the distribution of birds a1 sea and on rafting behaviour. DISTRIBUTION OF COLONIES It was known that the island held a large breeding population of Cory's shearwaters, and that xhere is an accesssible colony on the llheu da Vila, but it was not known whether any other colonies on and around the main island are suitable for the type of studies that were planned. Visits were therefore made other to parts of the coast, including Baia de Sao Louren~o, Baia de Tagarefe and Anjos. Althought large "rafts" of birds were seen on the sea in those areas during late afiernoon, the presumed breeding colonies were on steep islets and cliffs. However, visits made to Ilheu da Vila showed that this island has sufficient, easily accessible nests for a successful study. DISTRIBUTION AT SEA The value of the dietary studies planned for August/Septernber, 1990, would be greater if the~e were some indication of the areas in which the birds collected their food. A preleminary study of shearwater distribution at sea was therefore made during the journey by Portuguese navy frigate from Ponla Delgada to Santa Maria. The sea on both sides of the ship was scanned by eye from a location towards the stern. Birds seen were checked and counted using a 10x40 binocular, and observations were recorded in a consecutive series of 10-minute blocks from the beginning to end of the journey. The presence of cetaceans was also noted. Figure 1 shows the number of birds counted on the sea or in flight in each ten minute block. The maximum number was seen at 18.30 off the north-west coast of Santa Maria, probably representing birds beginning to gather in rafts prior to going ashore to their breeding colonies. but also coinciding wirh the shelf edge around Santa Maria. The small peak at 15.50 coincided with the shelf edge around Siio Miguel and that at 17.30 was associated with the presence of a whale and twenty dolphins. RAFTING A characteristic of a number of seabird species, including shearwaters, is "rafting" behaviour. or the gathering in flocks on the sea off the breeding colonies prior to going ashore. Few studies have been undertaken of this behaviour, and it  was considered that it may be an important component of the Cory's shearwater's time budget in relation to foraging behaviour and energy needs. 11 was thought that. if birds have difficulty finding enough food. because of food scarcity or the demands of young in the nest, the time spent feeding would increase and the start of rafting may be delayed. Two sets of observations were therefore made as pilot studies in relation la the monitoring of rafting behaviour: I - birds at sea, within a 45" arc, counted by telescope (magnification 25x1 from the quay at Vila do Porto on the 14th. June, 1990. A count was made at 15 minute intervals from 15.30 to 18.45. The results (figure 2) show a low initial density, followed by a steep rise from 17,JO to a maximum at 18.30. It is interesting lo note the relation between the numbers of birds present and the presence of cetaceans in the area, but the Iater high numbers are related to the rafting behaviour of the birds, a raft of 50-100 birds being seen on the sea in the direction of llhCu da Vila at 18-24. (no observations were made at 17.00 and 17.15). 2 - observations were made on the 15th. June, 1990 from a point on the cliffs overlooking IlhCu da Vila, from 78.10 to 19.00, and from 20.50 to 21.30 (figure 3). The first raft of the birds was seen at 18.10 and numbers on the sea rose rapidly to 250 at 19.00. During the period 20.50 to 21.30 the rafts moved gradually towards and behind the ithku at 21.44. (on the night of 16h. of June, observations on the illleu showed that the first birds came ashore at 21.303. It is interesting to note the Iengih of time, i.e. 3 hours 20 minutes, between the first rafts forming (18.10) and the going ashore of the first birds (21.30). This suggests that the shearwaters have no difficulties in finding sufficient food a1 this time of year.

Some Studies of Cory's Shearwater Calonectris diomedea, around the Island of Santa Maria.

Background and Methods Sera were tested for Brucella spp., Leptospira spp. and Toxoplasma gondii antibodies in 68 free-ranging New World monkeys from a forest fragment of the Brazilian Cerrado. Results and Conclusion All animals were negative for Brucella spp. and Leptospira spp. However, 75% of Alouatta caraya and 16.6% of Callithrix penicillata were positive for T. gondii. The implications for conservation and health management are discussed.We would like to thank the Wildlife Management (WLM) team for their support with the sample collection. The authors would also like to thank to Fundação de Amparo  à Pesquisa do Estado de São Paulo — FAPESP for financial support (Process number 2011/ 08149-8 and 09/51466-4; 09/53561-4). We also thank Dr. Chris Gardiner for constructive comments
