Juvenile Greenshanks are noisy, easily startled, waders, who take off shouting out their ‘tew tew tew’ calls in husky teenage tones at the slightest provocation. They are not hard birds to identify, with grey and white plumage and long, slightly upturned bill and long grey-green legs. The rump is white, as is the back, unlike the smaller Wood Sandpiper and Green Sandpiper, which both have square white rumps. Crossbills are exceptionally early breeders in the early spring and seem to spend the rest of the year wandering around in flocks looking for the best feeding grounds. They are most frequently encountered in areas of mature conifers, but during August, they may also be encountered flying over in small flocks, repeating their famous ‘chup chup’ contact calls. Only adult males are brick red, with younger birds being various shades of green, like the females and the streakier, browner juveniles. As devourers of much seedy material, they need to drink clean water regularly, and even clear puddles in suitable habitat can be a good place to look for drinking birds.
