Birds of Siquijor

The earliest collection of birds on Siquijor Island was made by the Steere Expedition to the Philippines in 1887-88, when the collecting party worked on Siquijor island in February, 1888. Thirty-seven bird forms were recorded, including three endemics: Loriculus pkilippensis siquijorensis, Hypsipetes s. siquijorensis and Dicaeum trigonostigma besti. F. S. Bourns and D. C. Worcester of the Menage Expedition to the Philippines (1890-93) next collected on Siquijor. They recorded 81 forms of which 44 were additions to the island's avifaunal list, including one more endemic, Zosterops everetti siquijorensis, the fourth on the island. This collection raised the total known bird forms on Siquijor to 87. Andres Celestino next collected on the island in September, 1907, and in April and May, 1908, for the Philippine Bureau of Science. He collected a total of 62 bird forms of which 9 were additions to the island's avifaunal list, making a total of 96 bird forms known from Siquijor as of 1907. Recently collections have been made on the island on several occasions by parties from Silliman University, headed by Professor Rabor and sponsored mainly by Chicago Natural History Museum. The island was visited in December, 1952, May-June, 1953, December- January, 1953, and December, 1954. Dr. Rand was with the collecting party in December-January, 1953. Collecting was done chiefly at Lilo-an and Tag-ibo, in and near patches of forest, but collections were also made along the Po-o River (Lazi municipality) from near the coast up to Barrio Cangumantang in the interior, close to the center of the island. These most recent collecting activities yielded 67 bird forms collected and 5 sight records. Of the number collected, 13 forms have been added to the avifaunal list of the island 9 resident and 4 migrant. A new subspecies of the yellow-bellied thickhead, Pachycephala philippinensis siquijorensis, was described, representing a fifth endemic subspecies. After deleting several doubtful records such as Cuculus canorus and Cacomantis merulinus the Siquijor list stands as 107 forms (106 species plus 1 subspecies) ; of these 83 are Philippine forms and 24 are migrants. The list of migrants may be considerably extended by future work, but the list of resident species is probably fairly complete.
