An Early Winter?

As I write this, the first "winter storm" of the season has just begun. Wind gusts occasionally shake the trees across the street and rain pitter-patters against the roof. By tomorrow evening, we're supposed to have received 2-3 inches. And if the 10-day forecast is calling for little sun. We very well may be in for an early winter this year.



One of the telltale signs of mid-Fall is the return of winter sparrows. The most numerous in this area are the Dark-eyed Junco (above). As of the last writing, I was occasionally seeing one or two in the yard, which most likely bred locally. However, I have been hosting a half-dozen on a regular basis for the past couple of weeks. More will likely appear over the next 4-5 weeks. Another one of our common migratory sparrows, the Golden-crowned, was spotted last weekend. I hope to see more in the upcoming weeks. Non-migratory Song Sparrows have also been visiting the yard for at least the past week. Song Sparrows tend to inhabit wooded or riparian areas during the breeding season, but disperse afterwards and often visit backyard feeding stations in the winter. I was also surprised (and fortunate) to observe an unusual migrant. A hatch-year Chipping Sparrow spent at least two days in the backyard a couple of weeks ago, before (presumably) continuing its journey southward. I managed to get several nice photos of this individual. In the upcoming weeks, we should be seeing White-crowned Sparrows as well.

This hatch-year Chipping Sparrow stayed with us briefly a couple of weeks ago.

Large flocks of American Goldfinches from early September through mid-October are common here. However, Pine Siskins typically do not show up until November or December. I was not surprised to see that we've been hosting two since about mid-September, but I was a little more surprised to see 14 at our feeders this morning. These numbers are more typical of late November or beyond, but there may be a non-weather-related reason why they're here so early this year. I've read a few reports that the conifer seed crop in the Central Cascades is poor this year, and think it's likely that this is why they're here so soon. It's possible that other conifer specialists, such as Evening Grosbeaks and Red Crossbills, may irrupt into the Valley this winter. That would be a heck of a treat for us.


The occasional Pine Siskin in October is to be expected, but...


... a flock of them suggests that something is up. Given the reports of the poor conifer seed crop in the Cascades, this may be a big year for irruptive finches.

One of the more irregular feeder finches, the Purple Finch, has also been representing in larger-than-expected numbers this season. Purples tend to move through urban yards in the early fall and early spring, and my experience has been that March and April are the best months for them. So I was surprised to see one in late September, and even more surprised to see two different individuals a couple of weeks ago. The individual in September hung around for a few days, but the latter two apparently did not stick around. I have no idea when I'll see one again, so these pleasant surprises certainly were appreciated. Evening Grosbeaks, highlighted in the last post, are apparently still making their way through. One individual (a female or hatch-year) was spotted at the bird bath last Sunday. With this year's failing conifer crop, it's possible that they may flock to the feeders later this winter.

American Goldfinches, pictured here earlier this month, are flocking to the feeders in more manageable numbers now (10-30, rather than 50-80). My wallet thanks them.

While all of the summer warblers have passed through, our Yellow-rumped Warblers have moved in from the mountains and at least one will likely stay to visit our suet feeders later this winter. Both subspecies (the white-throated "Myrtle" and the more common, yellow-throated "Audubon's" have been spotted in the yard and at least two individuals are chasing each other around, vying for territory.

Our neighbor's apple tree has continued to act as a magnet for fruit-loving birds this month. Flocks of a couple dozen Cedar Waxwings have been common for the past few weeks, and they've recently been joined by a few American Robins. Unlike the Eastern half of the country, Robins are not as prevalent in this area and are infrequent yard visitors in most places.


Both adult...


... and juvenile Cedar Waxwings have been enjoying apples this fall. Yum.


This hatch-year Robin concurs that apples are delicious.

Other year-round residents who typically don't hang around in the yard during breeding season have also graced us with their presence recently. These include our resident woodpeckers, the Downy and the Northern Flicker. Attracted by the large flocks of goldfinches, Cooper's Hawks are also visiting the yard on a semi-regular basis now. Steller's Jays, one of my favorites, are still occasionally stopping by for peanuts. Originally spotted at the beginning of the month, I'm still seeing the occasional Chestnut-backed Chickadee at the suet feeder.

Chestnut-backed Chickadees, always an elusive yard bird for me, are stopping by every once in a while.


If you look really hard, you'll find an immature Cooper's Hawk hidden behind the leaves and branches. This individual managed to pick off an unfortunate goldfinch moments prior to this photo being taken.

It's been a great beginning to the fall/winter bird season so far, and hopefully our luck will continue. Until next time...

Oktoberfest

Like the Germans consuming massive amounts of food and drink in late September/early October, our yard has become a veritable Oktoberfest over the past week. Both neotropical migrants and locals moving out of their breeding areas have inundated the yard. This is easily the most lively early Fall I've ever witnessed.



To underscore the awesomeness of the past week, the Evening Grosbeak (above) - a bird that I've hosted for a grand total of one day since the mid-1980s - has visited my yard for two consecutive days now. And they've visited at least four times today. Wow.

Another one of our irregular natives has also made a big splash recently. Cedar Waxwings breed in our neighborhood and can be found in small numbers here and there in the summer. But they flock in the late summer, right around the time that our neighbor's apple tree offers ripe fruit. A flock of ~10-15 have been visiting the apple tree several time per day since Friday. In contrast, Purple Finches head deep into the forests to breed and stray into less wooded (sometimes urban) areas afterwards. I typically don't see them until mid-October (if at all in the Fall... they're more conspicuous in March/April), so I was pleasantly surprised to see a female/juvenile at our feeders last weekend. A mature male was spotted this afternoon. Another forest-breeder/yard-feeder species, the Pine Siskin, has returned as well. Two began joining our flocks of 40+ American Goldfinches a couple of weeks ago and they're still showing up daily. These may have bred locally, but it's difficult to tell. In addition, our Juncos have returned from the Cascades and surrounding foothills. We're still waiting for the other winter sparrows.

The return of Dark-eyed Juncos means that summer is dead.

Several local breeders that disappear in the summer have also returned. These include Spotted Towhees, Red-breasted Nuthatches, Northern Flickers, and Chestnut-backed Chickadees (a new species for this yard).

Neotropical migrants have mostly made their way through at this point. Because of this, I was pleasantly surprised to see a female Black-throated Gray Warbler foraging through the neighbor's apple tree last weekend. I was even more surprised to spot a male in the same tree this morning.


This female Black-throated Gray Warbler was a pleasant surprise.




This blurry Townsend's Warbler might be the last one that we see until November.

While we're still waiting on our winter sparrows, our first winter warbler made a surprise appearance. Townsend's Warblers breed in the Northern Cascades, Northern Rockies, the Yukon, and Alaska. They winter along the Pacific coast, from Washington down to Baja California. We're close enough to the coast to enjoy them in the winter, but our first arrivals typically aren't until Thanksgiving. While I've seen them locally as early as mid-October, I was a little surprised to see on high up in the neighbor's tree during the last week of September. So we'll see how this plays out. Perhaps this is the sign of an early winter, and perhaps we just got lucky this year.

Freshly-molted Starlings look really nice, but they still eat way too much of my suet.


Our friendly Red-breasted Nuthatches have returned!


Chestnut-backed Chickadees are native to this area, but are a new species to this yard.

In addition to the high numbers of notable avifauna that we've hosted recently, we were pleasantly surprised to see a large, furry Western Gray Squirrel in the yard this morning. Our neighborhood is overwhelmingly populated by the more diminutive Fox Squirrel. Western Grays are native to the region, but tend to inhabit more rural areas. A brash individual jumped from our roof to our trellis (and back) this morning. Their enormous busy tails crack me up.



Wow, so who could ask for anything more? Well, I'm greedy and would like some more Evening Grosbeaks, some California Quail, and a couple of Red Crossbills to photograph for my next post. But even if that doesn't happen, I'm still very thankful for what I have. Until next time...

Fall Cometh

Signs of autumn abound. The sun is well hidden behind the horizon when the alarm clock sounds, and twilight sets in hours before bedtime. Temperatures dip into the 40s at night and struggle to hit 70 in the late afternoon. Some days are overcast, even rainy. Yes, our very short summer (it was still overcast and rainy in mid-June) is just about over. Thankfully, exciting events in the yard help compensate for it.



While migratory species such as the Yellow Warbler shown above have been prominent (and will be discussed shortly), the most conspicuous showing right now are the large flocks of American Goldfinches. "AMGOs" begin to flock in large numbers after their (rather late) breeding seasons ends. This is typically from mid-September through mid-October and, as we've seen before, they can really take over a yard at times. So I was rather surprised to see the flocking winter numbers (30-40) at the end of August. Halfway through the first week of September, their numbers were ranging from 30-70 at a time. I typically don't see these numbers until the end of the month or early October. Some of this could be attributed to the larger yard that we currently have, and/or the more open area of our new neighborhood. That said, I can't help but wonder if we may be getting an early winter this year. It's been cooler and more rainy over the past two weeks than what we typically experience at this time of the year. Of course, that's a small sample size, so who knows. Anyway, the AMGOs have been eating approximately $15 worth of sunflower and nyjer per week, and I've been refilling the feeders approximately three times per week. And, of course, sunflower shells are all over the ground now. That'll be fun to clean up. Lesser Goldfinches are still hanging around in small numbers.

While watching large flocks of goldfinches is nice enough, migratory species that stop by the yard are my primary source of enjoyment. And the past few weeks have not disappointed. Black-headed Grosbeaks, discussed in the last installment, had a very strong showing this spring/summer. As of five days ago, they were still passing through, though they'll be gone for good very shortly. A couple of weeks ago, we hosted a hatch-year. It was the first that I'd ever seen.

... a female Yellow Warbler follows suit shortly afterwards

Migratory warblers are always a good time. Our most prominent "summer warbler," the Orange-crowned, made an appearance last month, but the best showings so far were from Wilson's Warblers. At least one male and at least one female have made appearances on five separate occasions since the very end of last month. I was very pleasantly surprised to also see Yellow Warblers stop by one days late last month. Both a female and a juvenile appeared on the same day. While I'm still holding out hope for a Black-throated Gray to move through, most of the summer warblers have moved south at this point. We'll likely see our wintering Yellow-rumped Warblers next month.

Despite losing many forest-specific species (Brown Creeper, Chestnut-backed Chickadee, Red-breasted Sapsucker) after moving out of our old neighborhood last year, I've been pleasantly surprised at the number of meadow/riparian species that have stepped in to replace them. These include the two warblers photographed above, and also flycatchers (both Empidonax and Tyrant). Earlier this year, Hammond's Flycatchers and Western Wood-Pewees were spotted hawking insects in the yard (the latter on multiple occasions). But the most prominent and surprising flycatcher has been the Willow. I don't know what it is, but migratory Willows have really taken a liking to our yard. We could've just as easily hosted the same number of Hammond's or Pacific-slope Flycatchers. Strange, but no complaints.


Willow Flycatchers will use anything for a perch, whether it be this old TV antenna thingy...


... or a thorn-covered rose tree branch.

Oddly enough, at least one of my old conifer-specific buddies seems to have followed me here. Steller's Jays (above) breed in the conifer-dominated hillsides around town, and even up at several thousand feet in the Cascades. Even at our old place, Steller's Jays only stopped by when they were en route to or from their higher-elevation breeding grounds (basically October, November, and March). So I was doubly-surprised to have seen two different individuals here in the yard several times over the past week (the last was just a few minutes ago). The fact that they seem to be moving out of their breeding ground (at least, locally) this early again suggests a possible early winter. The poor conifer crop that I've been hearing about in the Central Cascades may also be a factor. Downy Woodpeckers, who also tend to breed elsewhere, have also made something of a comeback over the past couple of weeks. There has also been a noticeable post-breeding dispersal of American Crows, and some of their offspring have been hanging around the yard. No nuthatches yet.

Western Scrub-Jays are the second most frequent yard visitors at this point.

In other news, Rufous Hummingbirds have been slowly tailing off, to the point where I'm going to take down the second nectar feeder now. They should be completely gone by this time next month. Black-capped Chickadees and Bushtits are still abundant. House Finch numbers have remained approximately the same.

I'm going to be really busy with work soon, so this will likely be the last post for a month or so. Hopefully by then we'll host our first Ruby-crowned Kinglet, Townsend's Warbler, or Purple Finch. At the very least, Juncos should begin to move in from the hills. Until then...

Movement, Molt, and Youngsters

The past few weeks have taken us from mid-summer into the beginning of Fall. Changes abound, and I've been able to capture some of it with my snazzy new camera and lens.



Many migratory species have begun moving south recently. One of the most conspicuous in the yard has been the Black-headed Grosbeak. The male shown above was particularly interesting (to me), as it's the first molting individual that I had ever seen. (They always seem to lay low in mid-molt.) Judging from the head plumage, this individual appears to be a second-year male. This male was around for one day at the end of July and was never seen again. Since then, at least one female has visited on three or four occasions.

More migratory species graced us with their presence earlier in the month. But, of course, this was when I was in between cameras, so I didn't have the opportunity to get photos! Anyway, these transients included an Orange-crowned Warbler and a Western Wood-Pewee. Neither has been observed here since. In addition, a couple of Cedar Waxwings were feeding in the neighbor's apple tree the very afternoon after that shipped off my old camera. This kind of sucked, as I had several nice sun-lit shots against a blue sky. But waxwings are year-round residents, abundant in our neighborhood, and tend to hang out in flocks in that apple tree in the winter. I'm sure that I'll get another shot.

A slightly overexposed female Anna's Hummingbird enjoys our sugar-water feeder, after fending off multiple Rufous.

Male Rufous Hummingbirds are the deadbeats of the hummer world. They show up here in late February/early March, mate with the females that follow close behind, and then take off after the kids are born. No child support or anything. So that leaves mom and the kids to fend for themselves, and that's exactly what they've been doing here. There have been at least three individual Rufous and at least two Anna's going at it since the beginning of the month. Despite the fact that I have a window feeder on the opposite side of the house, the hummers all tend to "share" the more prominent feeder in the backyard. And when I say share, I mean fight tooth-and-nail. They spend so much energy fighting each other that they pretty much have to suck massive amounts of sugar-water afterwards. Seems like sharing perch space would be a more efficient use of energy, but what do I know. Anyway, it's been both interesting and entertaining. And I will be sad to see the Rufous take off for good next month.

This hatch-year Spotted Towhee stopped by the yard in late July, never to be seen again.


American Goldfinches were still rockin' the breeding plumage up until recently...




... but now the majority of them are all molty and nasty-looking. The seasons are definitely changing.

Late summer molt is exemplified well by American Goldfinches, particularly by the males. As shown above, males lose their brilliant yellow plumage and black cap. Females undergo a less dramatic change, transforming from light yellow/green to more of a light yellow/bronze color. Molt begins in late July and is complete in most individuals by mid-September. American Goldfinches also flock like crazy out here in September and October (50-100 visitors at a time is typical for us). We've already witnessed a sharp increase over the past few weeks, and are now hosting up to 18 at a time. This number will likely triple in a few weeks. I will definitely be purchasing a lot of seed over the next two months. To help with the anticipated demand, I've already put up a second nyjer feeder (left).

Starlings are also beginning to molt into their "speckled" winter plumage, while losing the yellow coloring of their summer bills. This transition is more subtle than that experienced by male goldfinches but, as shown below, juvenile starlings can look rather odd at this time of the year.

This hatch-year European Starling certainly caught my eye. I thought it was a juvenile Flicker at first!

That's about it for now. I'll have another update (and more photos) in a few weeks. And then I'll be getting very busy with work. (Though I'm sure that I'll be able to tear myself away to photograph migrants in October!)
