The mousebirds are birds in the order Coliiformes. They are the sister group to the clade Cavitaves , which includes the Leptosomiformes (the cuckoo roller ), Trogoniformes ( trogons ), Bucerotiformes ( hornbills and hoopoes ), Piciformes ( woodpeckers , toucans , and barbets ) and Coraciformes ( kingfishers , bee-eaters , rollers , motmots ...
Over geological timescales, changes in the shape of the oceanic basins and in land/sea distribution affect sea level. In addition to eustatic changes, local changes in sea level are caused by the earth's crust uplift and subsidence. Over geologic time sea level has fluctuated by more than 300 metres, possibly more than 400 metres.
Despite this, changes in the global sea level over the past 3–4 billion years have only been a few hundred metres, much smaller than the average ocean depth of 4 kilometres. Thus, the fluxes of water into and out of the mantle are expected to be roughly balanced, and the water content of the mantle steady.
Blue-naped mousebird perched. The blue-naped mousebird is a fairly small to medium-sized bird, measuring 33–38 cm (13–15 in) in length including the elongated tail of 20–28 cm (7.9–11.0 in), weighing 34–65 g (1.2–2.3 oz). [3] Adults have an ash grey plumage which is darker at top and lighter at bottom. [5]
The speckled mousebird is about 35 cm (14 in) long, with the tail comprising approximately half the length, and weighs about 57 g (2.0 oz). It is well-named, because it is dull-mousy brown in overall color on the back and on the head (including a prominent crest).

Still-water level or still-water sea level (SWL) is the level of the sea with motions such as wind waves averaged out. [6] Then MSL implies the SWL further averaged over a period of time such that changes due to, e.g., the tides, also have zero mean.
The U.S. will no longer allow the import of seafood linked to the bycatch of marine mammals. Each year, over 650,000 marine mammals, including seals, whales, and dolphins, are killed by ...
