Sunbathing Barred Owl

In the past few weeks two young Barred Owls have been regularly showing at my feeders and water feature during dry days.  More recently it has been only one.  This afternoon, alerted by a ferocious bark from the dog, we found the one had returned.  In fact earlier it had been overhead in the trees above the driveway where the song birds were equally as excited as the dog.  The owl does a lot of sitting, so it is hardly mesmerizing to watch, but today it jumped down from the bird bath and spread its wings on the ground to sunbath(?). 








More likely it was using the opportunity to rid itself of mites and otherwise keep its feathers in good condition. As you probably know already, owls' eyes are fixed in their sockets, so the only way owls can see what is taking place around them is by twisting their heads.  It looks odd, but it works, and along with an incredible sense of hearing and remarkable eyesight, they can easily locate their prey.

Nature's Waste Management

Several years ago on a hot summer day walk I came upon a young lady approaching from the opposite direction, peering at the vultures circling above with a look of fear and repulsion on her face.  She said in passing"I cannot stand those big birds".  I restrained my impulse to launch a pedantic lecture and responded that she really didn't want to live here in summer without them; they were critical to the well-being of this community.

True, they are no match as eye candy for Painted Buntings and Prothonotary Warblers, but they do the job keeping our warm and humid air clean enough for us to breath without gagging. The Turkey Vulture, with the bare red head and neck, is the larger of the two species, but strangely enough it feeds on small roadkill such as squirrels.  The smaller Black Vulture, the one with the white wing-tips, sometimes feeds in large flocks on the side of the road, and a gang can make quick work of something as large as a deer. 

However, the choice of foraging is related to how both species find food. Turkey Vultures have a much better developed sense of smell which may account for why they frequently find smaller carrion that Black Vultures miss. Turkey Vultures will arrive at a foraging site first, and the Blacks follow by observing the feeding behavior of early arrivals. 

The naked heads also serve a purpose. Since both birds can frequently be observed eating from the inside out (gross!), it prevents contamination of their feathers, and the potential spread of disease. In fact their very scavenger role in the ecosystem helps prevent the spread of disease to other animals as well as humans. So, while this treatise is about neither pretty bird nor pretty subject, woe unto our island without a healthy population of both species.

Vultures, often incorrectly called buzzards, are widely spread across much of North and South America, and are closely related to the endangered California Condor.  In fact it wasn't too many years ago that the American Ornithological Union grouped our majestic Bald Eagles with vultures. 

They are masters of the air as they hunt for prey.

Turkey Vultures in particular are not often seen flapping their wings, but both species hunt for rising columns of warm air called thermals.  Those currents keep the birds effortlessly aloft for long periods of time while looking for the next meal.

Unlike other raptors, the hawks and eagles, vultures feet are adapted for walking.  They have no sharp talons and depend entirely on the bill to tear into their prey. 
Interestingly, in  spite of their homeliness the Turkey vulture's scientific name Cathartes aura is often interpreted as 'purifying breeze'.  Indeed.

And Now a Rooster

For the past 10 days or so I have been hearing chicken-like sounds at Priest Landing in the early morning.  It didn't take too long to realize it was a rooster, either escaped or deliberately left there.  After the first two days I did not hear it for the next few. Naturally I assumed that one of the list of predators we have on this island got an easy meal.  Wrong...
