An unexpected visitor
My favourite group of birds is the raptors (birds that hunt or feed on other animals). It includes eagles, owls, kites and harriers. Unfortunately due to their finely tuned hunting senses, particularly sight, it is extremely difficult to get close enough to afford a good look. The best I can usually do is a grainy over-enlarged digital photo taken with a telephoto lens (see pictured left).
Birds, particularly raptors can ‘see’ things that are invisible to the human eye. The ability to see in the infrared means that birds such as eagles can see the thermals which they use to get lift in the air. Similarly, being able to see in the ultraviolet means that they can see the reflections of scent trails mammals (a.k.a. food) leave on the ground to navigate by.
Apart from Wedge-tailed Eagles (Aquila audax), which regularly soar up the valley, the most common raptor around our place is the Nankeen Kestrel (Falco cenchroides). It is often seen perched high in a dead tree surveying the surrounding paddocks or hovering in a stationary position before diving on some unsuspecting prey. Nankeen Kestrels are small falcons that feed mainly on small mammals, reptiles, birds and even insects.
Unexpectedly, a Nankeen Kestrel recently visited our bird bath (see photo right). The remote camera captured images so we could have a good look at the bird. It looks so close you can almost touch it (sort of like having front-row seats at a Justin Bieber concert – substitute your own music idol here).
And it’s another tick on the Birdbath visitors list.
