Bio-logical theme abandoned?


Nope, not at all! I just needed to provide a little background before we proceed to the next episode. In fact, the tie-in with the environment will become even more evident shortly.

Remember, as I shared some time ago, the spider must paralyse prey with a toxic injection, necessary to begin to liquify the prey for easier digestion. Often prey is wrapped in a silky shroud and left attached to the web for later consumption.

I narrowly escaped extermination by wriggling from the sticky bond of the web and made my way slowly up the branch, from which the web was slung, searching for cover in the neighbouring pine-oak woodland; a habitat I thought would be much safer for me.

Pine-oak woodlands are the preferred environment for the Acorn woodpecker, (Melanerpes formicivorus, derived from the Latin "Formica" ~ the genus of hymenopterous insects and "vorus" ~ eating. Drilling holes in the bark of either a pine or oak to store nuts, which later become haven for grubs and other insects, provides a steady food source for the woodpecker. The image on the right, a good example of the handy food storage work of the Acorn woodpecker, is known as a "granary".
