Some Tips on Identifying Some Winter Finches



As a follow-up to the Winter Finch Forecast and as a prelude to some really cool air coming into the area this weekend, here is a short discussion on how to identify the two most likely winter finches that may be seen.


This pine siskin shows the typical streaky plumage, strong wing bars and yellowish patches on the wings. This yellow may be very pronounced in some individuals and more muted in others. Photo by Jeff Lewis.




Seen with its close relative, the American goldfinch, the differences are apparent. The goldfinch has no streaking on the upper or lower sides. The two species often will occur together and have similar habits. The finch feeder stocked with niger seed will attract both species but sunflower seed feeders are just as attractive to them.  Photo by Taylor Piephoff                                                                                                                              



Purple finches should looked for now as well. This typical female shows the dark cheek patch bordered by two whitish stripes, resulting in a strong facial pattern. Purple finches are larger, bulkier, and more "bull-necked" than the house finches that are permanent residents in our area.

The male purple finch has more extensive raspberry color to the plumage. Note how the raspberry extends over most of the body, particularly from the breast down to the belly. Again, these birds are much more bulky than house finches. Photo by Kent Fiala





The male house finch has a more red or rose color than the purple finch, and the red is much reduced in coverage area. Note how the red extends to the breast but not to the belly. Male house finches are also brown on the upperparts whereas the purple finch has the shades of raspberry. Photo by Lee Weber




 This photo shows a female purple finch sharing a feeder with female house finches. Note how the streaking stands out compared to the house finches, which are plainer. Also note the plainer, unpatterned face of the house finch. The bulkier, bull-necked posture of the purple finch can be seen in this photo too. Photo by Lee Weber

Time to Start Looking for Winter hummingbirds!

It’s almost November first! Time to talk hummingbirds! For those of you who have been reading my Observer column for a few years, you should know what I am talking about. For those of you who may be new readers, this may strike you as an odd time of year to be discussing hummingbirds. Not so.
For the most part, our ruby-throated hummingbirds departed the southern piedmont around October eleventh. The water level in my feeder hasn’t moved since then. There may be a few ruby-throat stragglers still, but they will almost certainly be moving on soon. If you are still seeing a hummingbird at your feeder, you need to take a close look at it. Any hummingbird seen in Mecklenburg County after November first is much more likely to be a species that has flown in from the western United States. I suspect there are some of these long-range visitors with some of you right now. Please let me know if you are still seeing one.
As November wears on the likelihood of a hummingbird visiting you will increase. Keep your feeders up and maintained. Watch for fleeting visitors or dropping water levels, especially after the passage of strong cold fronts. Last November I received a dozen messages that hummingbirds had arrived after the passage of an unusually strong front mid-month. By New Years Day I had records of over thirty-five hummingbirds visiting feeders in the area. Some birds decided to move on after a day or so but some ended up staying almost to April, departing just in time for the ruby-throateds to come back.
The most likely species that you might see will be the rufous hummingbird. Males are pretty unmistakable, being almost all red. The females and immature, which are the most likely to be seen are more challenging to identify. Look for some reddish coloring on the flanks and around the tail region. If you get one, take a photo if possible and send it to me.

I will be writing more about wintering hummingbirds as the season goes on, providing updates on numbers and locations. 
Compare the two species in the photos below.


Female Rufous hummingbird by Jennifer Carpenter
In this photo of a female rufous hummingbird, notice the reddish plumage on the flanks and on the sides of the tail. This color is something to look for when examining late fall and winter hummingbird visitors. This is the most likely plumage these birds will be exhibiting.

In the photo of an immature male rufous hummingbird below, notice how most of the plumage is an unusual reddish-orange

Female Ruby-throated Hummingbird by Phil Fowler
In comparison, this female ruby-throated hummingbird shows no reddish plumage at all. This is the species that nests in the eastern United States. If you are seeing any type of hummingbird right now, let me know at piephoffT@aol.com

Winter Finch Forecast is Out


Every fall serious birders, both field birders and backyard feeder watchers, wonder what the coming winter will bring in the way of migratory and irruptive northern finches. The movements of northern finches such as pine siskins, purple finches, common redpolls, and crossbills can vary widely and wildly from year to year. For example, in some years pine siskins may dominate feeders even as far south as the Carolinas. In other years they may be completely absent.

Movements tend to be based on the availability of food produced by northern conifers. The better the yield of seeds the more likely the birds are to stay to the north. Poor yield or crop failure results in birds moving around more. And it really isn't limited to just finches. Other species like red-breasted nuthatches, waxwings, and blue jays are affected too.

Ron Pittaway released his Winter Finch Forecast for 2014-15 recently. Though predictions are generally for the northern and northeastern United States, some insight can be gained into what species we might expect to encounter here in the piedmont of the Carolinas.

Check out the full forecast here:

Maybe some pine siskins, shown here with a lone American goldfinch, will put in appearances at local feeders this winter.

Last Night a Big Night for Migrants Moving

Stepped outside this morning at 5:30 AM and was greeted by the sounds of numerous nocturnal migrants passing overhead. Most dominant were Swainson's thrushes, gray-cheeked thrushes, and rose-breasted grosbeaks. There were others but I am sorely out of practice deciphering the short, variable calls of the migrants.
Try it yourself. If you are an early riser, listen outside for just a few minutes around 5:30-6:00 AM. You can also hear them anytime after dusk through the night. You will know pretty soon if its a good migration night. You will hear birds. If you don't hear any after just a minute or two, try again the next night.
Below is a link to hear some thrush calls; as well as some other migrant grosbeaks, warblers, and tanagers.

Out with the Old, In with the New

The strong cold front that moved in last weekend was of the stuff birders live for. Since August serious birders have been waiting for the first strong front of the season. Oh, there have been some mini cool downs that caused some birds to move but the season had been notable for the absence of cold fronts with northwest winds. Such fronts sweep out migrants present prior to the passage and sweep in new ones. The birding landscape can change literally overnight. Birders well know this phenomenon and take advantage.
Last Saturday I was on the shores of Lake Norman off Exit 30 at Davidson. At daybreak I saw tightly packed flocks of both blue-winged and green-winged teal, some numbering over sixty individuals, flying high and low over the lake. For about an hour a flock of teal was never out of my sight. These hundreds ducks were pouring into and through the piedmont as a result of the stiff northwest winds. I also saw my first pied-billed grebe of the season and four common terns blowing around in the winds, also a season first.
The next day even more changes were evident. Winter birds appeared in the feeding bands of migrants. Yellow-rumped warblers, yellow bellied sapsuckers, and ruby-crowned kinglets replaced species that had departed. The front ushered in the first wave of sparrow migrants too. At Veteran’s Park I found the season’s first sizable chipping sparrow flock, a group of about twenty-five birds.
For weeks Eastern wood-pewees had been a numerous and conspicuous migrant. Eastern phoebes had been present in small numbers. After the front passed the numbers of these two species switched. Pewees became scarce while the phoebes became the dominant flycatcher seen. This fall I have seen more white-eyed vireos than any other year that I can recall, yet they were totally gone by Sunday. Small migrating flocks of blue jays could be seen winging slowly and steadily overhead, while migrating chimney swift numbers increased dramatically too.

There are still a few ruby-throated hummingbirds hanging around but their numbers took a nosedive too. I expect the numbers to have further declined by this weekend. Next, the sparrows and winter hummingbirds will arrive. More on that development in a few weeks.

Find a Berry-laden Dogwood Tree and Enjoy the Show

When I was growing up we had a large dogwood tree in the backyard that produced a good crop of berries almost every year. I remember just watching that tree for extended time periods and being amazed at the diversity of birds that visited to dine on the berries. Last week I was reminded of how attractive a productive dogwood tree can be when I visited Sheffield Park and Idlewild Road Park in search of migrants.
At Sheffield, a flash of orange caught my eye as a female or immature summer tanager hovered to pluck a berry from a large dogwood. Stopping to see what else might be around, I soon observed two Swainson’s thrushes, several American robins, a gray catbird, brown thrasher, and a rose-breasted grosbeak partaking of that tree. I was reminded that the woods of Idlewild Road Park have a large number of dogwoods and have been very productive in the past. I drove on over and headed down a trail to a nice hardwood forest with dogwood understory.
Immediately I saw a scarlet tanager in the dogwoods; then another, and another. A total of six scarlet tanagers and an additional summer tanager were all there.  A group four Eastern bluebirds flew in, another three Swainson’s thrushes, a wood thrush, some American robins, a red-bellied woodpecker, a Northern flicker, and downy woodpecker; all made for constant in and out action in the dogwood canopies.
Birds are attracted to the berries because of their red color. It is well know that hummingbirds like red, but clearly many bird species have the same affinity. Spicebush, a common lowland shrub, has red berries that are favored by birds, as does magnolia.

There are plenty of other species that love dogwoods too. I have seen gray-cheeked thrushes, veeries, red-eyed vireos, red-headed woodpeckers, yellow-bellied sapsuckers, and even pileated woodpeckers on dogwood. Dogwoods are clearly an important fall food source for hungry migrants. If you have a nice dogwood on your property, or know of a nice grove of multiple trees, take some time to watch for activity. You might see some unfamiliar species. 


Scarlet Tanager by John Ennis
All scarlet tanagers in the fall are greenish yellow with contrasting black wings. They look quite different from the brilliant scarlet and black males from the spring.









Summer Tanager by Phil Fowler
Female and juvenile summer tanagers are a more orangey color with less contrast between the wings and rest of the plumage.










Summer Tanager by Phil Fowler
Adult male summer tanagers in fall retain their bright red plumage year round. If you encounter summer tanagers, the majority will be female or juvenile plumaged.

A Nice Day in the Mountains

Hawk watching at Milepost 235 on the Blue Ridge Parkway (Mahogany Rock Overlook) September 21st produced birds, butterflies, and beautiful weather. Brisk northerly winds kept the smaller landbirds hunkered down, but made for good raptor migration conditions. By 11:00 AM the group had counted 95 Broad-winged hawks, 2 Osprey, 3 Sharp-shinned hawks, and 2 American kestrels. You had to be fast for many of the birds; the winds were zipping them past the counters at a fast clip for a while.
Ten birders from Charlotte made the drive to the watch site. Other birding groups from the state were represented too, with a total of around thirty people leisurely observing the show.
The winds died after lunchtime, and the migration action died with it. that gave us an opportunity to do a bit of butterfly ID. The warming temperatures allowed us to count 13 butterfly species just on the overlook lawn.
Counting will continue thru mid-November on good-weather days. If you are driving the Parkway in the next few weeks, drop in and check it out.
