Senegal Thick-knee
Burhinus senegalensis
Very large shorebird that is similar to Eurasian and Water Thick-knees, but with a longer and heavier bill. Also note the gray mid-wing panel without a black-and-white upper border. Immature Eurasian Thick-knees can also have a simpler wing pattern similar to Senegal, and identification of those birds best determined by structure and habitat. More connected to aquatic habitats than Eurasian Thick-knee, but not as much as Water Thick-Knee. Noisy, especially at night, producing a variety of loud whistles and trills.
识别特征
Senegal thick-knees are medium-large waders with strong black and yellow black bills, large yellow eyes — which give them a reptilian appearance — and cryptic plumage. They are similar but slightly smaller than the Eurasian stone-curlew, which winters in Africa. The long dark bill, single black bar on the folded wing, and darker cheek stripe are distinctions from the European species. Senegal thick-knee is striking in flight, with a broad white wing bar.

Collared Plover
Anarhynchus collaris
Uncommon, petite plover of beaches, coastal lagoons, lakeshores, gravel bars, and sandbars along rivers. Note slender black bill, brightly patterned head, narrow black breast band, and long pinkish legs. Despite the name, does not have white collar around back of neck like most small plovers. Typically found in pairs or as single birds; not in flocks like many other small plovers. At high tide they often roost with other plovers such as Wilson’s and Semipalmated plovers.
Banded Bay Cuckoo
Cacomantis sonneratii
Slender brown cuckoo with extensive fine barring and pale face and underparts. Found in lowland and foothill forests, where, like many cuckoos, it can often be inconspicuous in dense foliage. Listen for its two distinct songs, a high rising “smoke-yer-pep-per!” and a series of rising whistles.
Black Guillemot
Cepphus grylle
Small seabird of coastal areas of the North Atlantic and Alaska. Breeding plumage is entirely black with bold white patch on wings and bright red legs. Changes dramatically in winter to whitish overall with some dusky markings on body and black wingtips. Often found in shallower coastal waters including from shore. Dives to hunt for fish and invertebrates. Nests in crevice or burrow in a cliff or around large rocks.
