Three people birdwatching with binoculars. Birdwatching, or birding, is the observing of birds, either as a recreational activity or as a form of citizen science.A birdwatcher may observe by using their naked eye, by using a visual enhancement device such as binoculars or a telescope, by listening for bird sounds, [1] [2] watching public webcams, or by viewing smart bird feeder cameras.
Seawatching is commonly performed during bird migration seasons, and particularly when weather conditions are suitable. Successful seawatching is very dependent on the weather. [ 2 ] When the weather is fine, birds often stay out to sea, and pelagic trips are then a more effective way to observe them; if onshore winds combine with rain , birds ...
Altogether, the pelagic zone occupies 1,330 million km 3 (320 million mi 3) with a mean depth of 3.68 km (2.29 mi) and maximum depth of 11 km (6.8 mi). [2] [3] [4] Pelagic life decreases as depth increases. The pelagic zone contrasts with the benthic and demersal zones at the bottom of the sea. The benthic zone is the ecological region at the ...

These are pelagic seabirds that feed primarily by diving in the water. They breed in large colonies on coastal cliffs or offshore islands, nesting in crevices among rocks or in burrows in the soil. Two species, the tufted puffin and horned puffin , are found in the North Pacific Ocean , while the Atlantic puffin is found in the North Atlantic ...
Pelagornis sandersi comparison with the Andean condor (Vultur gryphus) and the wandering albatross (Diomeda exulans). The sole specimen of P. sandersi has a wingspan estimated between approximately 6.06 and 7.38 m (19.9 and 24.2 ft), [9] giving it the largest wingspan of any flying bird yet discovered, twice that of the wandering albatross, which has the largest wingspan of any extant bird (up ...
The Atlantic puffin and other pelagic birds are excellent bioindicators of the environment, as they occupy a high trophic level. Heavy metals and other pollutants are concentrated through the food chain , and as fish are the primary food source for Atlantic puffins, the potential is great for them to bioaccumulate heavy metals such as mercury ...
Outside the breeding season, they are pelagic, feeding on fish, squid and shrimp in the open ocean. They are long-lived for birds, living for up to 40 years. Historically, temperate Atlantic populations of the northern fulmar lived on the islands of St. Kilda, where it was extensively hunted, and Grimsey (Iceland).
