In winter (early October), the hazel dormouse will hibernate in nests either in the crooks of trees, nesting boxes or logs piles. Dormice are almost completely arboreal in habit, and rarely if ever become terrestrial. When it wakes up in spring (late April or early May), it builds woven nests of shredded honeysuckle bark, fresh leaves and grasses in the undergrowth. If the weather is cold and wet, and food scarce, it saves energy by going into torpor; it curls up into a ball and goes to sleep. The hazel dormouse, therefore, spends a large proportion of its life sleeping − either hibernating in winter or in torpor in summer.
Examination of hazelnuts may show a neat, round hole in the shell. This indicates it has been opened by a small rodent, e.g., the dormouse, wood mouse, or bank vole. Other animals, such as squirrels or jays, will either split the shell completely in half or make a jagged hole in it.
Further examination reveals the inner rim of the hole has toothmarks, which are at an angle to the hole for the dormouse. The toothmarks are parallel with rough marks on the nut surface for a wood mouse; the bank vole leaves parallel grooves with no rough marks.
Diet The hazel dormouse requires a variety of arboreal foods to survive. It eats berries and nuts and other fruit with Hazelnuts being the main food for fattening up before hibernation. The dormouse also eats Hornbeam and blackthorn fruit where hazel is scarce. Other food sources are the buds of young leaves, and flowers which provide nectar and pollen. The dormouse also eats insects found on food-source trees, particularl aphids and caterpillars.
Taxonomy
Deer live in a variety of biomes ranging from tundra to the tropical rainforest. While often associated with forests, many deer are ecotone species that live in transitional areas between forests and thickets (for cover) and prairie and savanna (open space). The majority of large deer species inhabit temperate mixed deciduous forest, mountain mixed coniferous forest, tropical seasonal/dry forest, and savanna habitats around the world. Clearing open areas within forests to some extent may actually benefit deer populations by exposing the understory and allowing the types of grasses, weeds, and herbs to grow that deer like to eat. Additionally, access to adjacent croplands may also benefit deer. However, adequate forest or brush cover must still be provided for populations to grow and thrive.
