Pig Nuts – when you are just too lazy to say the whole name

Pygmy Nuthatch in full view

Pygmy Nuthatch in full view

I have always been fascinated by Pygmy Nuthatches. When I was living in the Bozeman area, I rarely got to see the,, and as soon as I moved to Missoula, I have been seeing unreal numbers. They seems to be in each and every ponderosa pine, picking at the branch-tip cones. Like a circus act, they hang upside down and walk along the thinnest branches and needles. Their high-pitched calls pierce through the thickest stands.

Frenetic is the word most often used to describe the Pygmy Nuthatch, and it is indeed apt. They seem to be in constant motion, so you can imagine the difficulties that present the photographer. A small bird that feeds normally high in the canopy and it never slows down.

This winter season, I have observe the Pygmy Nuthatch foraging in the company of its cousins, the Red-breasted and White-breasted Nuthatches, along with Black-capped and Mountain Chickadees. Even in several occasions, Golden-crowned Kinglets joined the buffet.

Even with all of these frenzy of motion, the Pygmy Nuthatch lives within an incredible social framework. During these winter months, you will see the nuthatches traveling through the ponderosa pine forest in large groups that exhibit a high level of cohesion. Once they entered into breeding season, a breeding pair will typically have several helpers. These helpers are thought to offspring from the previous year. Outside of the breeding season, Pygmy Nuthatches communally roost in a cavity, and these jars (the collective term for nuthatches) of nuthatches can number up to 100 individuals. in fact, a lone Pygmy Nuthatch has never been reported to be roosting alone. Now that is what I call a social creature.

Americans Dippers gathering nest material

Short film and images of American Dippers gathering moss for their nest, which is located underneath a bridge that spans rattlesnake Creek in Greenough Park. Notice that the birds are consistently dunking the nesting material, namely moss. The wetting is thought to keep the moss alive and, therefore, more pliable. The American Dipper nest is ideally placed under a cliff overhang or bridge that is above the home range stream. The nest itself is a large (~1 foot), mossy dome, which consists of an outer shell of moss and grass, and interior cup is made of grass, bark stripes, and leaves. The entrance of the nest is towards the bottom of the dome. Both sexes are responsible for the nest construction, although the female chooses the nest location.

Really these are the last Snowy Owls for winter 2011-2012

I promise, I promise these are the last Snowy Owl images for this winter (probably). I feel incredibly fortunate have spent so much time in the company of these wonderful creatures. I wish that they remain safe as they begin their northward journey to the Arctic.

I see why they are called Red Crossbills

The emblematic character of the Red Crossbill

The emblematic character of the Red Crossbill

Of course, this title is presented with tongue firmly planted in cheek. They, or at least the males, are red, and the bills are crossed. These little finches (both Red and White-winged Crossbills) have evolved the only crossed bills of any North American bird. This arrangement of the mandibles is highly suited to prying open pine cone scales in order to remove the fatty, pine nuts within. The Maclay Flat area, near Missoula, MT, has been absolutely loaded with Red Crossbills this winter. They can seen flying in the typical bounding finch flight pattern between the treetops. They rarely seem to come down to our inferior level.

The most unique fact about the Red Crossbill is that the “species” may actually be comprised of up to 9 cryptic species. These “types” are divided by variances in the call notes and the morphology of the bill. These differences in bill size and shape seem to be related to the dominant type of conifer utilized as a food source. Types 2 through 5 and 7 have been found in Montana.

  • Type 2 - ponderosa pine
  • Type 3 - western hemlock
  • Type 4 - Douglas-fir
  • Type 5 - lodgepole pine
  • Type 7 – seems to be a generalist
The birds in these images seem to belong to the Type 2 group based on their call and habitat. The call resembles “kewp” in tone. The differences are rather subtle, and if, or probably more accurately when, the Red Crossbill is split along these Type lines, there will be many birders wandering around the forest in a bewildered state.

Harris’s Sparrow – another rare visitor

This past Friday, I was privileged enough to get the opportunity to visit a local backyard and get some half decent images of a Harris’s Sparrow. The sparrow was very retiring and it took roughly one and half hours to locate the bird in a yard side hedge. But once I found it, the show was on. Once I saw the bird, the distinctive black face cinched the identification, as it the only North American sparrow with a black hood and gray sides of the head. The little black-faced bird popped into view several times, which was such a treat even if the light was pretty cruddy and the distance too far. The Harris’s Sparrow was feeding upon cracked corn spread over the ground and also on birch seeds that had collected on the corrugated barn roof.

Harris’s Sparrow is observed in Montana about 10 times a year with Missoula being an area of relative density of sightings. This probably data anomaly most likely amounts to observation bias, rather any sort of preference by the Harris’s Sparrow. The peak month of Harris’s Sparrow observation is December, and most of the records are classified as transient or over-wintering birds.

After viewing the bird for about half an hour, I was on way home happy as I basked in post-birding glow. I got to wondering though, “Who the heck is Harris, anyways?” Edward Harris was a contemporary and benefactor of John James Audubon. He funding, at least partially, the publication of Birds of America for Audubon. He accompanied Audubon on his Gulf Coast expedition in 1837 and again during his Missouri River journey in 1843. Harris collected his namesake sparrow on May 4, 1843 near present-day St. Joseph, Missouri. Audubon quickly named the bird Friningilla harrisii, or Harris’s Sparrow. Later, it was learned that Thomas Nuttall had beaten the pair to the sparrow in 1834, and Nuttall had previously named it Fringilla querula, or the Mourning Sparrow. However, the common name assigned by Audubon won approval as the common name.

Know Your Poop #2

In this installment of Know Your Poop, we look at a pile of scat from the Blue Mountain National Recreation Area. This collection of pellets was found in the duff of a rather open ponderosa pine stand. They are about 1/3 of inch in length, and very uniform in oval shape.

Last Snowy Owls for 2012?

All of this winter, those of in Montana have been treated to an amazing display of Snowy Owls, especially in the Mission Valley. The owls have remained readily visible in a subdivision that sits above Polson and adjacent to agricultural towards Pablo. I have been able to visit on 7 different occasions, and I have taken 100s of images of the owls. But sadly, this enjoyment will come to an end as spring marches forward. The white owls will filter their way north of the arctic Circle, and I probably won’t see them again for another 4 years, when the lemming and owl cycle renews itself.

Rusty Blackbird at Lee Metcalf NWR

Today as a storm rapidly descended out of the Bitterroot Mountains, I spied a blackbird milling around on a small mud flat along Francois Slough. Upon further inspection, it turned out to be a Rusty Blackbird with that unique facial pattern, eye color, and overall coloration.
