THE NOCTURNAL BOREAL OWL

665-14-288Adult male is a night hunter and his prey consisting of small birds and mammals, such as this red-backed vole, are located by sight and sound.

Since nesting began, the male has been impossible to locate in the dark, damp forest near Slana, Alaska. But each evening he arrives at the nest site to deliver prey to the owlets. As the Alaskan days grow shorter, the male becomes active as twilight engulfs the stand of tall white spruce and poplar.  He is the sole provider for the five owlets snuggled inside a hollow stub.  The female abandoned her owlets when they were three weeks of age.  They no longer needed brooding so apparently her role is complete.

THE YELLOW-SHAFTED FLICKER

BOARS, THE MOST DANGEROUS GRIZZLIES?

15-11-14  Grizzly boar.

What happens in a close encounter with a grizzly bear is dependent on a lot of factors.  What you do is important but the most important factor might boil down to which of the local bears you have just run into. Not all grizzly bears are the same.  In fact they are all individuals, with different habits and temperaments.  Sub-adults, lacking experience and confidence, often travel with a sibling for extra security and status.  Females with cubs don’t like close surprises.  Sows with cubs attack people more often than other classes of bears.  These defensive attacks can be very serious but rarely end in death.

BOREAL OWL – PART 3

Yesterday I climbed a ladder twenty feet up to a natural hole in a decaying poplar within the boreal owl territory. I had found the male inside the cavity once, so I had always thought it was a likely place for a nest.  I took a quick look inside the cavity with flashlight and mirror but there was nothing inside.  A single gray, downy feather clung to the bark on the outside. The owl must have been spending some time there, I thought. When I looked around I was surprised to see the little boreal owl glaring at me from about ten feet away. It was clearly agitated that I was at the hole. A few minutes later as I photographed the owl from the ground, I suddenly heard the rapid calling of the male.  But it wasn’t the owl I was photographing.  There are two boreal owls here!

This morning just after six a. m. I returned to the owl territory. As I neared the poplar the cavity seemed to have vanished.  Through binoculars I could see the female was at the cavity entrance peering out at me.  What perfect camoflauge. It has been fifty one days since I first located the little male boreal owl.  Well, it seems that all his persistant singing has finally paid off.

NORTHERN FLICKERS PART 2

17Male northern flicker on spruce snag.

By the end of May one pair of flickers I had under observation had settled into a routine.  After their first egg was laid in the cavity the male no longer called from the nesting snag.  Now the calling and most of the drumming was taking place at another dead snag about a hundred yards to the north.

THE BOREAL OWL-PART 2

665-14-15Boreal owl with red-backed vole.

I have been continuing to keep track of the little boreal owl in Slana.  Its calling is falling off.  I no longer hear it in the daylight hours though my friend still reports hearing it during trips to the outhouse late at night. Less calling means it is much harder to locate but I am still finding it in the thick dark woods by searching an area of about one hundred yards by two hundred yards.  This small area seems to be its preferred daytime roosting area.  Slowly walk back and forth through the spruce and poplar forest and scanning every tree I find it about 30 percent of the time.  Once I was guided to its location by the calling of a couple upset boreal chickadees.  It is never in the same perch.

BOREAL OWL

665-14-4

I got a tip a couple years ago about a lady who had complained about being kept awake at night because the snipes were making too much racket.  But it had been too early in the season and I had a sneaky feeling it wasn’t snipes that were keeping her awake.

So, when I paid them a visit a couple weeks ago, I pulled out my I pod and speaker and asked if this is what she had heard.  “Oh yes”, that’s it she insisted.  “I could never forget that call.  And they’re back!  I have been hearing them again almost every night. ”

This was exciting news to me, because the call I had played was not the display flight of the common snipe.  Instead I had played the territorial call of the boreal owl.  She was quite surprised that it was a small owl she had been hearing. Continue reading

WILLOW PTARMIGAN

518-14-9

I’ve spent the last four afternoons looking for willow ptarmigan.  One of my photographic goals is to document more of their interesting behavior.  On top of that list of photo wants are photos of willow ptarmigan in their snow burrows.  Ptarmigan use snow to help insulate them against the frigid winter temperatures of interior Alaska.  Their use of snow burrows can occur any time of the day but most common as they prepare to roost for the night.  Willow ptarmigan are cyclic and their numbers have been quite low over the past two or three winters.  But as Justin pointed out, they seem to be bouncing back.
