“…For example, Espin et al (1983) showed a success rate of 0.88 and 0.96 for Black-winged Stilts feeding on molluscs (mudflat) and aquatic insects (water surface) in Greece, respectively. Similarly, Kumar et al (2021) observed success rates between 0.51 and 0.78 for River Lapwings ( Vanellus duvaucelii ) in India; differences in success driven by seasons and habitat type. Like Hawaiian Stilts, Black-winged Stilts and River Lapwings are primarily visual predators foraging on mudflat or shallow water (Espin et al 1983; Kumar et al 2021).…”

“…Similarly, Kumar et al (2021) observed success rates between 0.51 and 0.78 for River Lapwings ( Vanellus duvaucelii ) in India; differences in success driven by seasons and habitat type. Like Hawaiian Stilts, Black-winged Stilts and River Lapwings are primarily visual predators foraging on mudflat or shallow water (Espin et al 1983; Kumar et al 2021). It is possible that we underestimated success rate by missing very rapid swallowing movements of small prey, though Estrella et al (2007) note that Black-winged Stilts always begin the transport of prey items from the tip of the bill to the mouth with a sharp backward jerk of the head.…”

“…This fits with existing research that categorizes Hawaiian Stilts and related species as primarily visual foragers (Robert and McNeil 1989; Rojas et al 1989; Cullen 1994; Cavitt 2006). According to Baker and Baker (1973) and Kumar et al (2021), rapid, repeated pecking may be a sign of tactile rather than visual foraging. This helps explain why pecking was the most common tactic despite relatively low success, as tactile foraging is characterized by continuous searching (Robert and McNeil 1989).…”

Understanding habitat use on a fine scale is essential for the development of management plans for threatened and endangered species. Several heavily managed State Wildlife Sanctuaries and National Wildlife Refuges provide critical foraging habitat for the endangered Hawaiian Stilt, or Aeʻo (Himantopus mexicanus knudseni). The foraging behavior and habitat use of Hawaiian Stilts at Hāmākua Marsh State Wildlife Sanctuary, Oʻahu, Hawaiʻi was investigated. Foraging tactics, success, and microhabitat were recorded for 227 birds over 24 2-hr periods from September to December 2021. Hawaiian Stilts made the most foraging attempts in shallow (< 8 cm deep) water, and had the most success in intermediate (8-15 cm deep) water. The most commonly recorded foraging tactic was pecking, while the most successful was plunging. Visual tactics were both more common and more successful than tactile. The overall foraging success rate for Hawaiian Stilts in this study was 0.16, markedly less than success rates observed by other researchers in related species. It is possible that prey in Hāmākua Marsh is either less abundant or less vulnerable to capture than in other similar habitats. Our results suggest that future habitat management for Hawaiian Stilts should prioritize areas of shallow water and further investigate food availability.

“…Such results thus suggest that the pecking technique was a partially tactile hunting mechanism. This is because birds that used rapid pecking seemed to depend less on visual cues and more on tactile cues (Baker & Baker, 1973, Kumar et al, 2021. These rapid pecks may help the foraging birds to find suitable locations in which to probe and also allow them to catch prey at random (Pienkowski, 1983;Davidson et al, 1986).…”

Foraging Behaviour of Three Shorebird Species on Coastal Mudflats of Southwestern Sarawak

Many shorebirds are long-distance migrants and they congregate on intertidal mudflats for feeding throughout their non-breeding season. Despite being one of the key staging sites for migratory shorebirds, data on shorebirds foraging ecology in Sarawak is insufficient for the understanding of the interaction between shorebirds and their behaviour. This study aimed to determine the foraging behaviour of Whimbrel (Numenius phaeopus), Bar-tailed Godwit (Limosa lapponica) and Terek Sandpiper (Xenus cinereus) at Asajaya and Buntal mudflats. Data collection of this study was conducted at low tide, during two non-breeding seasons with a total of 12 months of sampling. Focal observations were conducted within a 50 m × 50 m quadrat. A total of 8 exclusive foraging techniques were observed for the three shorebird species, including: pecking, probing, picking, stabbing, snapping, submerging, sweeping and ingesting. Terek Sandpiper displayed all the exclusive foraging behaviours, whereas Whimbrel and Bar-tailed Godwit showed 7 and 5 behaviours, respectively. The three shorebirds also displayed non-exclusive foraging behaviours such as walking, preening and defecating. Spearman correlation test indicates a positive correlation between the foraging behaviours performed among three shorebird species. All three shorebird species adopted similar mixed foraging strategies comprising pecking and probing, with an exception on supplementary behaviours observed in Whimbrel and Terek Sandpiper. Principal Component Analysis (PCA) analysis showed a strong correlation between picking and ingesting behaviours, suggesting a high chance of foraging success with the presence of picking behaviour. The outcome of this study is crucial in understanding how shorebirds maximise their behavioural performance when foraging as well as to assist in formulating better conservation strategies for targeted migratory shorebird species and coastal mudflats.

“…Pecking was defined as the bill penetrating the substrate for less than one-quarter of its total length, whereas probing was defined as the bill penetrating the substrate for more than one-quarter of its total length. 27 Foraging techniques were further re-categorized as walk-halt (WH), walkhalt-pecking (WHP), walk-halt-multiple pecks (WHMP), walk-halt-probe (WHPro) and walk-halt-multiple probes (WHMPro). 27 Moreover, foraging success was further classified into four components: (1) walking rate: steps per minute taken by the lapwing during the observation; (2) foraging or feeding rate: total number of feeding attempts (pecks or probes) made by individual birds per minute; (3) foraging success rate: number of prey items taken per bird per minute; and (4) percent attempt success: calculated as the number of feeding attempts that resulted in prey consumption per lapwing per minute divided by the total number of feeding attempts made per bird per minute and then multiplied by 100 (with the help of original data).…”

This study monitored the temporal pattern of the diurnal foraging behaviour of yellow-wattled lapwing Vanellus malabaricus Boddaert, 1783 (Charadriiformes: Charadriidae) in different seasons (breeding and non-breeding) and habitats (uncultivated, cultivated, ponds and rivers). The focal observation method was employed to investigate the foraging behaviours of yellow-wattled lapwings. Foraging techniques showed non-significant (p = 0.85) variation in different habitat types; however, walk-halt pecking (WHP) was observed to be the most commonly utilized foraging technique across all habitats. Furthermore, foraging success varied significantly in seasons (p <0.05) as well as in habitat types (p <0.05). Due to the availability of ample food items, foraging success reached its peak in uncultivated habitats. We documented considerably high feeding rates in the uncultivated habitat in the breeding season due to the high prey abundance. Additionally, seasons and habitat both greatly affected the rate of walking. Uncultivated habitat represented the highest value of % successful attempts while the lowest value of % successful attempts was recorded in river habitat. Moreover, the % successful attempts were significant (p <0.05) in the breading season as compared to the non-breeding season. Finally, we found substantial (p <0.05) changes in temporal pattern with regard to daily foraging behaviour. The behaviours appear to be bimodal, with morning and evening types for both seasons and habitat types.
