I got to April before I realised I'm going to need a diary if I'm ever going to know where I have to be and what I have to be doing and when. The one my husband got me for my birthday last year is so gloriously full of blank pages for notes and scribbles that I've been using it just as a notebook, and I'm already up to August, so I need a new one. I got one last week, pretty much the last one in the shop, which happily happens to be the Natural History Museum one. It's fab.
Bats can be excellent midwives. An inexperienced mother-to-be was helped by a female roost mate who fanned her, appeared to give her instructions and, after birth, helped move the pup into a suckling position.
18 April : The first Willow Warblers and a Tree Pipit overhead showed that migration was slowly under way this morning, but still no sign of many summer visitors. Local insects on the other hand are enjoying the fine weather, and there are plenty of butterflies, hoverflies, and above all a variety of bees on the wing. More bees to follow...do bee do bee do...
The earth is divided into layers with
the crust, or lithosphere, being outermost,
the mantle in the middle and the core innermost.
Together the lithosphere and mantle
form separate plates that move relative to
each other. Because of streams of material
beneath the mantle, the plates are moved
either away from or toward each other.
Where they move apart, magma flows
upward forming new material in the earth’s
crust, but where the plates move together,
they thicken and form fold-mountains. If
one plate moves under another, a deep-sea
trench is formed.
Deposits of volcanic ash colour this view of the Meridiani Planum, captured by High-Resolution Stereo Camera on the Mars Express orbiter operated by the German Aerospace Center (Deutsches Zentrum für Luft- und Raumfahrt; DLR). The images give clues on the prevailing wind direction in this region of Mars.
