The diet and breeding density of 19 pairs of Common Buzzard Buteo buteo脗赂 were studied in relation to indices of lagomorph and vole abundance during June July 1993 in a range of habitats in southern Scotland. Lagomorphs, voles and birds formed over 70% of the food items analysed from prey...
Their habitat includes woodlands, scrubs, marsh bogs, farmlands, and even around cities and towns occupied by lots of people. These birds prefer to live in temperate climates. Common buzzards can be seen year-round in Scotland, Wales, and throughout England. They are especially active in the...
Common loons are birds that prefer colder areas close to water. They are most often found throughout Canada and are common in New England. In addition to Canada, loons are common to Alaska, Greenland, Iceland, and Scotland. They tend to live near smaller ponds during the summer, when they...

On a shorter term basis, the secretion of PRL is influenced by factors associated with incubation. For example, the introduction of an artificial egg into the nest of yellow-eyed penguins (Megadyptes antipodes), before birds normally start laying, stimulates PRL secretion in females (but has ...
Global poultry production has been estimated at 21 billion birds per year, producing 1.1 trillion eggs and approximately 90 million tonnes of meat annually (Blake and Tomley, 2014). Cockle shells are one of the two main shell types used in poultry grits (ground-up shell is mixed with ground...
Drowning is infrequently reported as a cause of death of wild birds and such incidents typically involve individual, rather than multiple, birds. Over a 21-year period (1993 to 2013 inclusive), we investigated 12 incidents of mortality of multiple (2 − 80+) Common starlings (Sturnus vu...
birds and whales, vocal elements in songs have a strong social basis and the expression of geographic variants can be associated with the species’ vocal learning abilities—the individuals within a population learn specific vocal elements through a process of cultural transmission, horizontal or ...
