owls - a natural, low cost rat control that won't harm pets or other wildlife
Interesting but useless facts; Owls have
twice as many bones in their necks as humans, enabling them to rotate their
heads 270 degrees (not completely around as the myth claims). A typical adult
Barn Owl (seen here in north Texas) can eat about 1500 rats a year, for only
the price of housing. A group of Owls is called a “parliament” of Owls, but
most people just call them a “bunch”.
for children: When selecting binoculars for
there are three key criteria:1. Choose one where the distance between the eyes (“IDP”) adjusts down
to a minimum of 50-55 mm.2. Avoid a
toy/compact model – these almost always have smaller focusing dials, which save
weight but are difficult for children to use.3. Steer clear of extra-high magnification and toward a greater field of
view, so a child sees more area and doesn’t just get frustrated.
The goal is to compensate for a child's decreased motor control, not just to make things lighter. “toy” binoculars are quite often
cheaply made, poorly constructed and have vastly inferior lenses. These built-in
flaws will quickly discourage a child fromusing them, since he/she can’t see much of what real binoculars disclose.
