Autumn 2019 Migration – 9 Nov 2019
The 12th Singapore raptor watch was held on Saturday, 9 November 2019 and involved 45 participants. The weather was fine. There were seven raptor watch sites and the numbers counted at each site varied from a high of 175 to a low of 43 birds. A total of 714 raptors were counted, including 562 raptors representing 10 migrant species (two species more compared to last year) and 93 raptors of 6 resident species. A further 59 raptors could not be identified to species level.
Most of the sites were the same ones as previous years, thanks to all the site leaders for their faithful support! The minor changes were the shifting of the Japanese Gardens site to Jurong Lake Garden, and a slight shift of the Tuas site to Tuas South Avenue 10. We also had an opportunity to add in Tuas South Link, where the records were distinct (based on timing of the birds) from the other Tuas site.
The highest number of raptors recorded was at Jurong Lake Garden (175 birds), followed by Telok Blangah Hill Park (147 birds) and Tuas South Avenue 10 (107 birds). The greatest diversity of migrant raptors was at Telok Blangah Hill Park with seven species, followed by Jurong Lake Garden with six species, and Puaka Hill with five species. The other sites all recorded three migrant species.
The peak hours for migrant raptors were between 11am to 12pm (133 migrant raptors) followed by a higher peak from 3pm to 4pm (194 migrant raptors).
The Oriental Honey Buzzard (OHB) were present at all the sites and claimed the top spot again, with 398 birds counted. The largest number of OHB were at Jurong Lake Garden (155 birds), Tuas South Avenue 10 (86 birds) and Tuas South Link (64 birds). There were 104 Black Bazas across five sites, with Telok Blangah Hill Park recording the most (57 birds).
A total of 34 Japanese Sparrowhawks were recorded across all sites. The 17 Chinese Sparrowhawks were recorded at three sites only, with the bulk at Puaka Hill, Pulau Ubin (14 birds).
Three Western Ospreys were recorded – two at Tuas South Link and one at Puaka Hill. Interestingly, two Greater Spotted Eagles were recorded, one at Jurong Lake Garden from 10am to 11am and one at Telok Blangah Hill Park from 12pm to 1pm – could these have been the same individual flying eastsoutheasterly?
Only one Grey-faced Buzzard and one Peregrine Falcon were recorded – both at Jurong Lake Garden; as well as one Common Buzzard and one Jerdon’s Baza – both at Telok Blangah Hill Park.
For the resident species, the total count was 93 birds of 6 species. The count for the resident raptors comprised 42 Brahminy Kites, 25 White-bellied Sea Eagles, 18 Changeable Hawk Eagles, 4 Crested Serpent Eagle, 2 Black-winged Kites and 2 Grey-headed Fish Eagles.
The figure below provides a snapshot of the number of raptors according to the three categories – migrant, un-identified & resident raptors, at the 7 sites.
A complete breakdown of the species counted at each site is shown in the table below:
Thanks to all the 45 wonderful birders which included National Parks Board staff, for spending their Saturday out in the open to count raptors. The following fantastic people led or assisted in the raptor count (apologies if anyone were to be inadvertently missed out):
