An application was made during the winter 2014-15 to upgrade the sea defences at Exmouth Pier Head at the mouth of the Exe estuary, UK (Figure 1). No waders occurred in the site. However, waders sometimes roosted at the north-eastern end of the Dawlish Warren Nature Reserve which lies on the opposite side of the estuary’s mouth to Pier Head (Fig. 1). Accordingly, there was concern that the construction activities at Exmouth would disturb roosting waders during the winter months when they may sometimes be hard-pressed to balance their energy budget, as exemplified by the European Oystercatcher Haematopus ostralegus L. on the Exe estuary itself (Goss-Custard et al. 1996) and more widely across its winter range (Goss-Custard & Stillman 2020). Very few birds were thought likely to be disturbed over low tide when the birds were foraging because most of the feeding grounds within the estuary and along the adjacent coast were >1km from Pier Head at which distance the sound would have been greatly attenuated (see below).

The Black-winged Stilt Himantopus himantopus superspecies consists of one to five species, with a near cosmopolitan distribution in warmer regions (Sibley & Monroe 1990, Pierce & Kirwan 2020, Robinson et al. 2020). There are two phenotypic forms in the Americas: Black-necked Stilt Himantopus [himantopus] mexicanus and Whitebacked Stilt H. [h.] melanurus. These are variably considered distinct species (Sibley & Monroe 1990, Ridgely & Greenfield 2001), melanurus a subspecies of mexicanus (Hayes 1995, Remsen et al. 2019, Robinson et al. 2020, this paper), or both as subspecies of the globally widespread Black-winged Stilt (Meyer de Schauensee 1970, Blake 1977, Hayman et al. 1991).

The laterally asymmetrical bill of New Zealand’s endemic Wrybill Anarhynchus frontalis is unique among birds and has inspired much debate regarding its evolution and functional significance. Despite this, only one previous study has attempted to quantify the range of individual variation in bill shape, but used a single metric of curvature (bill tip angle). Using standardized digital photographs of 40 live Wrybills, we explored a range of metrics of bill length and curvature to describe the variation in bill shape in greater detail. Like the previous study, we found no sexual dimorphism in bill shape, despite males being slightly longer-billed than females, and recorded similar variation in bill tip angle (16–23°). However, we found that this single metric under-represented overall variation in bill shape, due to significant differences in where curvature began and was most pronounced along the length of the bill. Principal component analysis indicated that at least three independent metrics were required to describe the shape variation among individuals. Subtle differences in bill shape could plausibly affect an individual’s relative success among the range of Wrybill foraging strategies observed in breeding and non-breeding habitats. Elucidating the potential behavioral and fitness consequences of this variation will require detailed foraging and demographic studies with individuals of known bill morphology.
