Kota Kinabalu, Sabah (August 3-5;12, 2025) Callyn Yorke

I visited four main areas in the Kota Kinabalu area: Tanjung Aru, Ramsar Wetland, Likas Beach and Lagoon, and the University of Malaysia Sabah campus. These were walking surveys done in the morning (0630-1100 hrs.). I used the online Grab Taxi service for transport to and from the C’Haya Hotel in Tanjung Aru. I also noted birds found in the vicinity of the hotel and in transit through KK. Due to increasing traffic congestion, high ambient temperatures and frequent afternoon thundershowers, I found that bird surveys were best done within two to three hours after sunrise.
Tanjung Aru (TA, August 3; 12, 2025: 0800-1000 hrs.; 0624- 0810 hrs. Overcast skies; 78F to 80F, wind SSW 2-10 mph.) – I walked the beach at low tide, surveying the shoreline (bird-less) and offshore waters (1 distant, unidentified tern). Birdlife was found near the entrance to the beach in adjacent coastal scrub and parkland habitat with an assortment of exotic trees and shrubs. Tall casuarinas and palms lined the beach; patches of coastal scrub occurred toward the south end of the shoreline. The walk terminated at fenced facility behind a rock breakwater (see the following satellite map image). A few joggers and other visitors were present in the area during my two surveys. I met a friendly group of students from China who were quite keen on finding birds. These delightfully enthusiastic girls turned up again when I was visiting Mt. Kinabalu National Park.


Rasmar Wetland (RW, 4 August 2025: 0725- 1040 hrs. Partly cloudy, 80F to 85F; wind SSW 2-5 mph). Initially, I walked around the parking area and entrance to the ecological reserve facility. The reserve entrance included a garden with lawns, mature trees and shrubs, some of which were flowering. The interior of the reserve was accessed by a network of boardwalks through a well developed, closed canopy mangrove, dissected by tidal channels.

Visibility was good due to the elevated boardwalk, an observation tower and bird hide, each at opposite ends of the mangrove. I spent a total of about one-hour divided between the observation tower and bird blind. Except for a maintenance worker on the boardwalk, I was the only one in the reserve. The facility was normally closed to the public that day (Monday). Luckily, the main gate to the reserve was open when I arrived by taxi and I was allowed to enter without having prearranged the visit.

Likas Beach and Lagoon (LBL, 5 August, 2025: 0740-0835 hrs.; partly cloudy, 78F to 84F, wind SSW 2-5 mph). I walked the paved bike path and part of the shoreline from the separate parking areas adjacent to the shoreline highway. This area is between the park entrance and north channel inlet (see following satellite image). A narrow, coastal strip included a nearly closed canopy grove of casuarinas, assorted ornamental shrubs and picnic areas. Offshore waters for birdlife. Birds on the east embankment of Likas Lagoon were partly visible from Likas Beach, and identifiable using a 10 x 42 binocular (a spotting scope would have been useful here). Due to heavy traffic on the coastal highway, combined with the lack of a pedestrian crossing, I remained on the Likas Beach side for observations of birds in the lagoon. There were probably birds in the lagoon that I overlooked.

University of Malaysia Sabah Campus (UMS, 5 August 2025 – continued: 0850-1020 hrs. weather – as in previous entry with increasing cumulo-nimbus). I took a taxi from Likas Beach to the UMS Institute of Tropical Biology (ITB). That facility is atop a hill in the northwest corner of the campus (photo). I walked the surrounding paved roadways bordering a well developed rainforest overlooking the seacoast of Kota Kinabalu. Gardens with ornamental and native flowering trees surrounded the buildings. I also visited the ITB Natural History Museum, which included labeled invertebrate and vertebrate collections with dioramas. Returning to the main campus gate was problematic. It required hitching a ride with an ITB evolutionary biologist specializing in isolated populations of land snails. From the main gate, a Grab taxi was readily available for the return trip to the C’hay Hotel in Tanjung Aru.

BIRDS NOTED
- Striated Heron Butorides striata 10 individuals perched motionless, low in the mangrove forest, usually over small pools of water, RW.
- Eastern Cattle Egret Bulbucus coromandus 1 on east embankment of lagoon with GREG and LIEG, LBL.
- Gray Heron Ardea cinerea 1 in low flight over lagoon, LBL.
- Purple Heron Ardea purpurea 1 in low flight over lagoon, LBL.
- Great Egret Ardea alba 30 greg. on east embankment of lagoon with LIEG; 10 greg. individuals and a small flock at edges of mangrove clearings and perched on snags in large lagoon next to the bird hide, RW; on shore and breakwater. In the bay, individual birds riding on small boats operated by fishermen with nets, LBL. The latter case appeared to be an unusual example of symbiosis. The egret may be taking fish from the fisherman’s catch (kleptoparasitism) and/ or taking only fish that would ordinarily be thrown back (commensalism). In at least this instance, it was clear that the fisherman and his Great Egret mascot, tolerated each other’s close proximity, indicating a rather stable symbiotic relationship (photos).
