- Mar 1, 2005A bird will be mentioned!
On Sunday we came upon small animal tracks on the snow looping in many, many
circles beside a shelterbelt. The loops got smaller and smaller, and in the
middle was a dead vole.
There didn¹t seem to be any other predator tracks and the body was
Some parasites alter their hosts¹ behaviour in order to get the host eaten
and the parasite passed on to another host: this happens in snails which are
eaten by birds (the parasite causes the snail to seek light, climbing up a
stalk), and mantids which get eaten by fish (the parasite causes the mantis
to enter water).
So I¹m wondering if the vole was forced up on top of the snow and to make
lots of tracks, running around exposed for at least an hour I¹d guess, so
that it might be picked up by a coyote or bird.
Sunday we also saw a Snowy Owl and many Horned Larks near Kronau.
