2.16 Curlew<br />

2.16.1 Foraging<br />

Core foraging range<br />

Curlew tend <strong>to</strong> forage within 0.5 and 1km of nest sites, with regular foraging up <strong>to</strong><br />

1.5km (authors’ experience).<br />

2.16.2 Nesting<br />

A study of breeding curlew at Monk’s Moor, Upper Teesdale, found that first-year<br />

burned areas were used as nesting habitat at a greater frequency than would be<br />

expected based on the availability of this habitat (Robson et al., 1995).<br />

2.16.3 Display flights<br />

Defence of terri<strong>to</strong>ry is by both sexes, but mainly the male (Cramp & Simmons, 1983).<br />

The male marks the terri<strong>to</strong>ry using an undulating display flight, which usually involves<br />

a low flight that rises steeply on fluttering wings, followed by a brief hovering and then<br />

gliding back down. This is then repeated (Cramp & Simmons, 1983). Male display<br />

flights can be up <strong>to</strong> 1.5km from the terri<strong>to</strong>ry centre (authors experience).<br />

2.16.4 Competitive behaviour<br />

No information on pertinent <strong>to</strong> <strong>connectivity</strong> was found.<br />

2.16.5 Habitat use<br />

Chick habitat choice<br />

Curlews breed in upland areas in Britain, generally up <strong>to</strong> 550m a.s.l., and<br />

occasionally up <strong>to</strong> 760m a.s.l. The Monk’s Moor study which radio-tracked four<br />

broods (Robson et al., 1995) found chicks showed a preference for first-year burned<br />

areas, as well as Juncus effusus flush, based on a greater use of these habitats than<br />

would be expected based on their availability (Robson et al., 1995).<br />

2.16.6 Winter behaviour<br />

No information on pertinent <strong>to</strong> <strong>connectivity</strong> was found.<br />

2.16.7 Dispersal<br />

Chick dispersal<br />

Median distances from the nest for the four broods radio-tracked in the Monk’s Moor<br />

study were 99m, 196m, 196m, and 267m (mean: 190m), whilst maximum distances<br />

were 185m, 207m, 318m and 489m (mean: 300m) (Robson et al., 1995).<br />
