Two of a kind

Two of a kind
Two days ago, 24 February 2015, I called in again at Fish Creek Park to see if anyone had been able to find the tiny, popcan-sized Northern Pygmy-owl(s). I was in luck and, although the light was bad, the little owls put on quite a performance. This included a few things that I had missed on other days, such as a perched on a fence post (photo posted yesterday) and both owls very briefly sitting on a branch for just a few seconds, side by side. Unfortunately, I was standing the "wrong" side of the tree, so only saw them from behind. Luckily, the female did turn her head for just a moment. There is quite an obvious difference in colour with this pair, with the male (on the right) being a more rusty colour, and he's smaller than the female. You can see the two black "false" eyes on the back of his head. A poor quality image, taken in bad light, but I was happy to get any at all. There were long periods of waiting in between the various bits of activity, so one needs a huge amount of patience : )

This fence post photo I posted yesterday was taken shortly before I left the park, after watching and waiting and hoping that this little female would eventually fly down and catch a Meadow Vole. Instead, she simply flew over to a fence post, which in itself was a real treat. I loved the background colour from patches of dead leaves still hanging on the bushes.

"Northern Pygmy Owls are 'sit and wait' predators, that hunt mainly by vision, diving down onto prey on the ground and driving the talons into the prey's throat. They will also attack birds in shrubs, crashing into the hapless victims. Most prey is carried off in the feet to feeding sites. Birds are usually plucked before being consumed. They often eat only the brains of birds and the soft abdomen of insects. One of these little owls can carry prey weighing up to 3 times its own weight.

The Northern Pygmy Owl feeds on a wide range of small prey including small mammals, birds, and reptiles and amphibians. Voles make up the bulk of their diet, with birds comprising most of the rest (mainly songbirds, but as large as a California Quail). Other small mammals include shrews, mice, chipmunks, bats, moles, young rabbits, and weasels. Insects may be very important when they are most abundant. Other prey taken are toads, frogs and small lizards and snakes.

During winter, surplus prey is cached in a cavity, often in large quantities. Summer caches are usually much smaller.

Pellets are very small, averaging about 3cm long. They are formed only occasionally as these owls don't consume large amounts of fur, feathers, or bone. The pellets tend to fall apart shortly after ejection." From OwlPages.

Posting really late today, after lunchtime. To put it mildly, I really need to try and change my sleep pattern so that I'm getting to bed hours earlier and not waking up so late in the day!
