Owls

My favorite order of birds is by far the owls, also know as Strigiformes, which includes Tytonidae (the Barn Owls), and Strigidae (the "typical owls," all other owls besides Barn Owls). I recently bought a new camera body, but haven't had time to go searching for any birds to photograph.  So until I can get back out there, enjoy some of my favorite owl photos taken with cameras I have retired! 

Burrowing Owl: Boise, Idaho

Northern Saw-whet Owl: King's Gap State Park, Pennsylvania

Elf Owl: Madera Canyon, Chirachua Mountains, Arizona

Western Screech-Owl: Santa Barbara County, California

Snowy Owl: Cambria County, Pennsylvania

Great Gray Owl: Sax Zim Bog, Minnesota

Northern Hawk Owl: Sax Zim Bog, Minnesota

This week of raptor watching...

While I was hoping for a Rough-legged Hawk to make its was down ridge this week, my site wasn't incredibly productive over the last few days for raptors.  Admittedly, less raptors moving through the state in general means that I will probably not see as many as the bigger sites anymore; my site has a poor viewshed, and I count alone, increasing the chances that a few are getting by me. The week started out very warm, and despite the great thermal production, no buteos were taking advantage of them.  I guess in November, warm weather might mean "I made it!" to a raptor. While a lot of raptors end up in South America and southern North America for the winter, a decent number of them actually stay in Pennsylvania and other "northern" states, finding enough food and space to suit their needs.  Meanwhile, most of the local Turkey Vultures have left the area, leaving me with an empty sky. Later in the week a small cold front moved through, but I wouldn't have known it based on raptor numbers, except for the fact that I was freezing my butt off.  Friday and Saturday were the kind of days where you can wear basically every article of winter clothing you own, but the wind still finds its way right through you.  And, November can be a bitter-cold month in PA. The winds are very inconsistent; one second you are enjoying the sunshine like a fat duck sunning on the bank of a pond, and the next second you are nearly knocked over by a 30 mile an hour gust of wind.  If you are lucky, its also snowing, and the fun fluffy snow you were just enjoying, nearly thinking "I love winter!" turns into tiny little ice pellets in a snow squall that seems to find the few places of bare-skin that you haven't covered. Needless to say, at the end of the day you can feel a little frost-bitten.  So, the highlights of this week were not raptors for once.  My first Tundra Swans of the season came through, and Common Loons were fairly numerous.  My favorite non-raptor to watch was a porcupine that wanders pretty aimlessly around the area.  If he's not rustling around the field pulling down the remaining green vegetation he can reach, he's sitting high up in a maple gnawing on its branches. Meanwhile the rut is in full swing, and deer are everywhere.  I've been visited most days this week by a huge 8-point buck, and he is always hot on the trail of any doe that wander by.  There is also a set of older fawns and their mother that visit the nearby field, eating anything left that is green and out of reach of the porcupines. Thankfully for them, I am not a hunter, and I'll continue telling the hunters I see that I haven't seen much of anything besides birds :o)

Zone-tailed Hawks

After hawk watching mostly in the east over the past few years, I really love going out west and seeing the raptors that just aren't present on the east coast.  I spent part of the last two summers in Arizona, and my favorite raptor to see there is the Zone-tailed Hawk.

Zone-tailed Hawks breed from Northern Mexico into New Mexico, Texas, and Arizona. EBird also shows records in California, Utah, Colorado, and Oklahoma, in addition to a sighting from October of  1976 in Nova Scotia!  (This particular bird was present from September 24th through October 4th).  Any well-planned birding trip through Texas should include a small detour off I-10 on the "Sheffield Loop," also known as Hwy 290.  The Ft. Lancaster Overlook at the Sheffield Rest Area is one of the most famous and well-known areas for Zone-tailed Hawks.  Alex and I made a stop here in the summer of 2010, and within 5 minutes of being at the rest stop, Alex spotted a Zone-tailed Hawk!  At first, I didn't really believe that it was one; their flight behavior is almost exactly the same as that of a Turkey Vulture, with a strong dihedral and plenty of "rocking" movement.  But through the scope, I could clearly see its black and white barred tail (also down the road from here, we found a pair of Scissor-tailed Flycatchers on a nest!).

(darker purple=more frequently reported)  see eBird for complete interactive map

Many people are using eBird lately, so probably the best way to find a Zone-tailed Hawk is to search for recent sightings in the breeding season, go there, and wait it out.

I've only ever photographed one adult Zone-tailed Hawk. Apparently juveniles appear more brownish than adults. Also, juveniles have many light bands on the tail, while adults only have three. 

I've only ever seen four Zone-tailed Hawks. One was on the Sheffield Loop in Texas, and that was an adult.  While working on the Yellow-billed Cuckoo Project near Cibola NWR, Alex and I saw a juvenile Zone-tailed Hawk.  And this past summer in south east Arizona, on our 5 day birding trip, we saw one in the Chiracahuas, and one in Tucson (the one in the pictures below).  Both were adults.

American Robins, Eastern Bluebirds, and the Asian Lady Beetle...

Since last weeks Golden Eagle push (check it out over at Nemesis Bird), raptor migration has been fairly slow.  About the only thing I've seen in any large numbers are Harmonia Lady beetles, also known as the Pumpkin Beetle, or Asian Ladybug.  Apparently this is the time of year they seek a warm place to spend the winter (preferably, your attic), and their jumping off point seemed to be my hawk watching tower.  On one day, it looked like it was literally raining lady bugs.  I'd put the binoculars up to my face only to see a massive bug on the lens, then rightfully plink it away.  I've spent a good amount of time plinking them off my tower over the last few days, but the warm temperatures are just really encouraging them to explore every nook and cranny of it.  Spiders like to use the tower as a jumping off point, too.  I've never been a big fan of any spiders, but its hard not to watch a spider throw its body off the edge of what I can guess is the spider-equivalent of a million story building.  Spiders of all sizes walk to the corner of the tower, stick their little abdomens into the air, then shoot out a few strands of silk that get carried off into the wind.  The spider continues sending off strands while it spins in a circle, and eventually, it has created a parachute that is strong enough to lift it off the tower. And, it goes sailing off into the open sky.  This happens in a very short time period of about 30 seconds.  I'm hoping if I force myself to watch this enough times, I can get rid of my unjustified arachnophobia.

Other migrants this past week have included a ton of American Robins.  It seems like every few hours, a massive flock descends into the forest, and it sounds like an army of people approaching as they rustle through the leaf litter for insects and worms brought out by the sun.  Meanwhile, Eastern Bluebirds have been passing overhead, and often stop on the wires of the nearby meteorlogical tower to catch a few things to eat themselves.  By the time they move on, their bellies usually look quite full.

Many Eastern Bluebirds didn't take the time to stop...

At least they gave me something to photograph!

Another EABL coming in for a landing...

And while I haven't had any Snow Buntings land, I've had quite a few pass over in small flocks.  While hawk watching at Jo Hays Vista the other day, Alex actually had a few land right in front of him!  They are really attracted to the gravel parking lots that are usually adjacent to roadside hawk watches, as are American Pipits and Horned Larks.  Check out the Snow Bunting pics over at Nemesis Bird.

And finally, reports of Rough-legged Hawks are coming in for the state, and I can at least hope one will get blown my direction sometime soon.

Eastern Screech-Owl at Bear Meadows

Two nights ago, I joined a group of local young birders on an "owling" trip to Bear Meadows.  Our goal was to draw out Northern Saw-whet Owls, Eastern Screech-Owls, Barred Owls, and Great-horned Owls.  It was a chilly night, and the full moon probably kept most of our small owls quiet and hidden, who would rather go unnoticed by the larger owls on such a bright night.  In the distance, we were answered by a Great-horned Owl, but it wasn't concerned enough with the territorial intrusion of our playback to make an appearance.  At one of our last stops of the night, we were finally answered by a territorial red phase Eastern Screech-Owl, likely the same one the group had here about a month ago.  While we all thought his "trilling" and "whinny" calls were pretty darn cute, he meant business, and is likely constantly defending his territory from a stream of migrant small owls that were almost certainly hidden nearby.  Believe it or not, this was the first good look I have ever had at a Screech Owl!  I've only seen them in my headlights late at night, and I've never been present on a night of 'Saw-whet banding when one was inadvertently captured. While I have heard plenty while doing owl work at night in PA's woods, it is nearly impossible to approach a small owl at night without disturbing it.

Try finding a bright rufous owl on roost in the fall...nearly impossible! Check out this post on Alex's old blog where he found 2 Screech Owls on roost in an oak tree.
