Pileated Woodpecker Scaling Signs, Up Close

Pileated Woodpecker's are numerous on Sanibel Island.

We followed this female Pileated Woodpecker one morning.

We saw her scaling bark off Mangrove Trees.

Scaled areas near where she was feeding

She landed and began to pound away at the bark,

striking blows beneath it,

and a large piece of bark fell away.

At one point, we saw her long tongue extended out.

She would poke her bill in at the edges of the scaled bark.

You can see her tongue going beneath the edge of the bark, here

and here,

and in this close-up.

We had an opportunity one morning at the Sanibel Lighthouse park to follow a Pileated Woodpecker. We watched the female in the above photos work over some Mangrove Trees, partially dead from damage done by Hurricane Charley in 2004. She whacked off chunks of bark and at one point we saw a fairly large chunk fall after she struck repeated blows. Later we went to some of the areas she had scaled and felt the bark and found it was tightly adhered to the tree. It was hard for us to pull any off.



One of the great things about digital photography is that you see amazing things when you blow up your photos. Our photos showed the long tongue of this female Pileated that tapers at the tip. How cool is that. Reminds us of seeing the tongues of Ruby-throated Hummingbirds when we watched through our binos as they perched near our feeders in NH. In the Birds of North America Pileated Woodpecker account written by Evelyn L. Bull and Jerome A. Jackson, it says the Pileated, "uses long, extensible, pointed tongue with barbs and sticky saliva to catch and extract ants from tunnels." This female was using her long tongue to poke into the sides of the scaled areas. Intriguing. At one point, we saw some tiny ants going under the bark and wondered if that was what she was getting. What an unusual opportunity we had to witness up-close-and-personal the feeding techniques of this female Pileated Woodpecker. There are independent researchers who are now searching for the similar looking Ivory-billed Woodpecker in LA and trying to determine its presence by distinguishing the type of scaling signs it does from that of the Pileated Woodpecker. Intriguing idea.

Cackling Goose, Would You Know One?

Cackling Goose, hutchinsii subspecies


All above photos, Cackling Goose, hutchinsii subspecies

Cackling Geese create excitement for birders when they show up in the East, and this is the time of year they often appear. Look carefully when you see a flock of Canada Geese, and maybe you can find a Cackling Goose! See my other blog post here. These geese, who mainly nest in the arctic, look like very small Canada Geese, but are a different species. There are 4 subspecies of Cackling Goose. It is thought that the subspecies who usually shows up in the East is the nominate subspecies, Branta hutchinsii hutchiinsii, (also sometimes called "Richardson's Goose", "Richardson's Cackling Goose" or "Hutchins's Goose"). The above are photos I took in western Massachusetts on 11/8/09 is of the hutchinsii subspecies (confirmed by experts). ID of Cackling subspecies emphasizes head and bill shape, with hutchinsii having a ratio of bill length to depth of about 3:2. This bird in my photo has a short bill, a short, steeply rising forehead, a rather flattened crown rising to a bit of a peak at the back of the head, all characteristics of the hutchinsii subspecies. Most hutchinsii also have a narrowing of the white of the cheek patch at the level of the eye, also visible on this bird. This bird also has a very pale breast, as have the majority of hutchinsii. The back and sides are also pale, the back does not appear darker than the sides. There's noticeable pale edges to the wing covert feathers, creating pale diagonal lines.

Cackling Goose, unknown subspecies

Cackling Geese cannot always be identified as to subspecies, as with the above and following photos of an individual I photographed in Ohio (east of Toledo) in May 2005. Several experts concur that this might be a hutchinsii subspecies or possibly an intergrade between the taverneri and hutchinsii subspecies, but it cannot be definitively identified. To quote the excellent article on Distribution and Identification of Cackling Goose Subspecies by Mlodinow et al. "though birds breeding on the continental Arctic slope from the Mackenzie River west are thought to be taverneri, the precise border between taverneri and nominate hutchinsii has not been defined, nor has the degree of potential or actual intergradation between the two (J. Leafloor, J. Pearce, D. Derksenpers. comm.)."

This bird shows a more rounded head than the hutchinsii bird in my top photo, with a more gradual slope from the bill to the head, more characteristic of taverneriTaverneri subspecies have "stout and somewhat triangular bills". The breast of this bird is pale. Taverneri are "typically medium-gray-breasted, becoming darker on belly/flanks" according to the article. However, sometimes they can have pale breasts.

Here's the neck fully upright in an alert posture of the goose. The head looks faintly flattened and there's white flecking at base of the black neck, suggesting a very thin white neck collar. The article estimated that only 2-5% of taverneri adults have a neck collar and that about 10-20% of hutchinsii can have a neck collar.

Here's another posture with the head looking somewhat flattened. Note that under the chin you can see a thin black line running from bill to the black neck, called a gular stripe. This is sometimes seen in a small percentage of hutchinsii, whereas 40-75% of taverneri have a gular stripe according to the article.

Here's another posture where the neck looks short.

Cackling Geese of the hutchinsii subspecies mainly winter along the Gulf Coast from southeastern Louisiana down into Mexico and also from eastern Colorado to eastern New Mexico through western Texas and into Mexico. Of the Cackling Geese that show up outside of their normal wintering range and stray to the East in small numbers, almost all reports have been of the hutchinsii subspecies. They have been reported from Indiana, Ontario, western New York, southern Quebec and Nova Scotia down to Virginia with a few reports to North Carolina, South Carolina and a few from Florida.
Taverneri subspecies winters in mainly Washington and Oregon, although some may winter in the continent's center. There are few reports of taverneri in eastern North America. There's a record from Onondaga county, New York, Sept. 2004, Janesville, Wisconsin, Oct. 2004, Amherst, Mass. Oct. 2007 and maybe the same bird in Middlefield Conn. Nov. to Dec. 2007 for photos of this bird see here.
The other two subspecies of Cackling Geese are leucoparia and minima. Minima (called Ridgway's Goose) is the smallest and darkest of the subspecies and winters mainly in western Oregon and Washington and central California. Only a handful or so of reports for minima exist for east of the Mississippi and are for North Carolina, Illinois, Connecticut, Alabama, Virginia and Tennessee. Leucoparia (called Aleutian Goose) a medium-sized Cackling, has a broad, white, complete neck collar on all adults. It winters mainly California and a little in Oregon and there are no winter records for east of the Mississippi River that we know of.
So keep looking at Cackling Geese in the East, there may be other subspecies showing up besides hutchinsii.

For excellent and complete information and photos of all 4 subspecies, see our The Stokes Field Guide to the Birds of North America, page 12.

Happy Thanksgiving to All!

Wild Turkey

These Wild Turkeys are headed in the right direction.
Happy Thanksgiving Everyone!

About Wild Turkeys:

* Wild Turkeys populations were once in decline but turkeys were reintroduced and have recovered and now Wild Turkeys occur in every state (but not Alaska) and in parts of Canada.

* Wild Turkeys live in forests and eat berries, buds, seeds, insects and nuts, especially acorns. They can scratch the ground to find food. They may come to bird seed under feeders.

* Wild Turkeys roam together in flocks in search of food. You may see them along roadsides and in fields and crossing roads.

* In spring, male turkeys perform courtship displays in fields. They fan their tails, puff up and strut and give their familiar gobbling calls. The female raises the young chicks, who can follow the female after hatching and soon can find food on their own.  Females and young form into groups and roam together.

Enjoy Wild Turkeys when you see them!

Another Big Year for Snowy Owls? Stay Tuned!

Snowy Owl sightings so far in November 2017, ebird map. Will this be another big year for Snowy Owls to come down into the U.S. possibly in big or record numbers? In some years Snowy Owls leave their far northern areas and come into this country in search of food, possibly because food is scarce in their usual area but also in years when there is a population boom. Some are saying there was a high population of owls on their nesting grounds this year, so possibly many may leave. Stay tuned and report your sightings to ebird. And keep your distance when photographing them so as not to disturb the owls!! My blog post below was done in December 2013 when a historic irruption was underway.





Snowy Owls can come down into the U.S. in possibly historic numbers in some years (note, all photos on this post taken with long telephotos lenses from a distance, mainly from a car, so as not to disturb the owl.)
We saw 9 Sat. on the NH and MA coasts. This one was sitting in a parking lot.
I love the soft feathers around the bill, all the better to keep it warm.
This owl preened
and sat in the wind.
 Grassy flat areas, dunes, marshes, and anything like its tundra home are the habitats these Snowy Owls seek out.

Here it is in front of a New Hampshire Parks vehicle.
There are actually two of then on this breakwater way out there.
Here's a closer view taken with the powerful telephoto lens (up to 4800mm) of the Canon SX 50.
There is a mega irruption of Snowy Owls coming down from their tundra areas taking place now, with reports flooding birding listserves across the northern parts of the U.S., southern Canada, and there has even been a Snowy Owl reported in Bermuda. Birders in St. John's, Newfoundland are seeing 150 Snowy Owls in a day. There more owls on the way and this could be a historic event. You can see a map of Snowy Owl sightings on ebird.

Saturday we saw 9 on the NH and MA Coasts, with birders reporting many more owls from those areas. Owls are showing up more in coastal areas but also some from inland. They are attracted to flat or rolling, grassy or marshy tundra-like habitats. We saw our owls in coastal dunes and marshes, but they can be in other places. There are Snowy Owls showing up at airports, and one was seen hunting the grounds of the Budweiser plant in Merrimack, NH. They can perch on buildings, rocks, houses and lamp posts overlooking favorable habitat. Keep your eyes open, they could be anywhere!

If you do see a Snowy Owl do several things:
* Report your sightings to ebird, the national database that tracks birds, so this event can be well documented.
* Do not get close to the owl to view or photograph it so as not to scare it away or harass it. These are birds that have left the far north because there is not enough food there. They are hungry and may be starving and need to conserve energy to hunt for food.
*Enjoy watching and appreciating these, usually rare, Snowy Owls for this is a special event. Some of these birds, unfortunately, may not make it if they do not find enough food.

Snowy Owls breed in the far north and in winter some come down into Canada and the northern half of the U.S. Sometimes when there is a food shortage in their usual areas, they may irrupt in large numbers and move south as they are doing now. They are diurnal hunters and eat lemmings and other small mammals and rodents, sometimes ducks and seabirds.
Male Snowy Owls are generally white overall with a suggestion of grayish barring. Females are heavily barred overall and young birds are the darkest of their sex with first year females being the darkest.

To learn more about Snowy Owls, and how to identify other birds (including all those you photograph!!) see our new field guides:


The Stokes Field Guide to the Birds of North America contains over 3,400 bird photos (many of them from me and other top bird photographers) and is the most complete photographic guide to those birds ever done.


It is also available as eastern or western regional editions,

The Snowbirds Have Arrived!! Welcome Them At Your Feeder

Dark-eyed Junco

Yesterday we noticed large flocks of Dark-eyed Juncos coming through on their migration. We had some birder friends from AZ visiting and everywhere we looked clouds of juncos were fluttering up. Another friend of ours asked, "since the snowbirds are here does that mean its going to snow??"
Oh no, not yet, not the "s" word. It will snow this winter. Just because the "snowbirds," (another name for juncos), are here, doesn't mean it's going to snow now.
Dark-eyed Juncos are named snowbirds because of their plumage colors of gray and white. They have "gray skies above and snow below." In other areas of the country juncos may look slightly different.
Some juncos may stay and winter with us here, in NH. Others will continue their migration and may show up at your feeders, so start looking. Juncos like to feed on the ground or from low platform feeders and come to millet and mixed seed.

Short-eared Owls are Migrating Now!



Short-eared Owl


Short-eared Owls are migrating now and one was recently seen on the NH coast. Interesting that in the past just about this time (Oct. 27th 2013) we were at our nearby hawk watch site, Pack Monadnock Raptor Migration Observatory in southwest NH, and saw a Short-eared Owl migrating, a first record for that site. It was migrating during the day and popped up above the mountain in the midst of some ravens. Much excitement at seeing the first one there and it was a thrill. Recently on NH birds list serve, a Short-eared Owl was reported from migrating on the NH coast, a more common place to see this uncommon owl.

Little is known about Short-eared Owl migration according to the authoritative source on bird behavior, The Birds of North America online.

The Short-eared Owl is one of my favorite owls. This medium-sized owl lives in open habitats, such as tundra, grasslands, fields, marshes, prairies and savannas, where it hunts small mammals. It breeds mostly in the far North and parts of the West and can be seen in winter in many parts of the country.

All the photos above, except the small bottom photo which is of the owl over Pack Monadnock, are of a Short-eared Owl I saw on Christmas several years ago in the marshes of Salisbury Beach, MA. This owl mostly hunts at night, sometimes during the day. I was lucky it was out and gave me photo ops. This owl flies erratically, like a moth, and courses low over the ground. 

So keep your eye and ears open for Short-eared Owls and you may add to the information on its migration.

NO Birds At the Feeder?? Here's Why!

Dark-eyed Junco

Many people have been reporting a lack of birds at their feeders and right now we are not going through the bird seed as we were in later summer when the baby goldfinches were gobbling all.

The main reason for birds not being as abundant right now at feeders here in New England is because this has been wet year and mild fall and there seems to be a superabundance of wild food available, including pine cones, other cones, seeds, fruits, berries. The birds just don't need the feeders, plus since it has been warm their calorie requirements are lower. As you know, birds in the wild do not ever get all their food entirely from feeders. They go around their winter ranges each foraging in their own species way. Chickadees stay in a small fixed flock in a winter range of about 20 acres and glean insects and larvae from bark, as well as eat nuts and seeds. They visit feeders in their winter territory. In extremely severe weather however, when wild food has been depleted and or is covered with ice, then chickadees will visit feeders more and sometimes it can be life-saving.
For those of you, including us, that are addicted to seeing birds at our feeders, there are some birds coming to feeders now and here's how to entice them.
Dark-eyed Juncos are one of the most common feeder birds in the country. These northen breeders come down into the U.S. in winter. By us, some stay the winter, some migrate farther south. Juncos are a type of sparrow and love eating at or near the ground.

We built this brush pile and placed it about 15 feet from our bird feeder. It is about 4 feet high and 12 feet wide, made of saplings and even seed heads from our perennials. We sprinkle millet on the ground in front of it and in it. The Juncos and White-throated Sparrows just love it and visit often. These species naturally feed on the ground in the wild, and this set-up simulates their wild feeding situation plus gives then the cover of the brush pile to hide from predators. Millet is a tiny white seed enjoyed by sparrow species. It is not the favorite food of chickadees (black oil sunflower is). Even though we sprinkle it on the ground we monitor it and clean up any old seed. Mostly all our seed is in feeders and seed cleanliness is very important to the birds. We also put millet in platform feeders, and sometimes the juncos and other ground feeding species feed there. The brush pile also offers protection from predators to all the other birds who visit the feeders.

Blue Jay

Blue Jays also are coming to feeders now big time. You'll also see them flying across highways as you drive around. Jays have a habit of carrying off seeds and acorns in fall to cache (hide) them for later use. Jays have a mixed reputation; they can eat birds eggs, but they are also great alarmists, warning of hawks, and other birds may benefit from that. We enjoy their beautiful colors against the late fall landscape.
Meanwhile, have patience and keep feeders clean and filled, you want the winter feeder regulars to know you're there when they need you. Once the weather turns cold your feeder regulars will be back.

How to Help Bluebirds Survive Winter!

We have Eastern Bluebirds visit us occasionally in late fall and even check out some of their nesting boxes from the past breeding season. They even grab a snack of the dried mealworms. They usually move on when the weather gets really bad.


Bluebirds may sometimes remain in some northern areas in winter, much to people's surprise. Here's some tips for bluebird enthusiasts, on how to help bluebirds survive in winter.

1. Bluebirds can roost together in bird houses to keep warm. Insulate your bird houses by closing off all cracks, drainage holes, etc., with some sort of insulating material so less drafts and cold get into the bird house. Just leave the entrance hole open. Remove insulation in spring before breeding. Face bird houses away from prevailing winter winds.

2. Bluebirds mainly eat fruit and berries in winter. Plant your property with an abundance of crabapples and native, berry-producing shrubs such as viburnums, dogwoods and hollies (like winterberry holly). Place these berry plantings in sunny, protected areas, blocked from winter winds. The bluebirds will have a warm place to eat and use less precious energy.

3. Some bluebirds will come to food such as, hulled sunflower, suet, dried mealworms, and some of the many "bluebird meal mixtures" or nuggets. Generally most bluebirds do not learn to do this. You can certainly try putting out these foods, but your best bet is to have lots of berries planted in your yard.

4. Bluebirds like water (may help with processing the berries) and will visit bird baths and heated bird baths. In general, when it is very severely cold, some people think it is a risk for birds to bathe. Holding off on the water, or placing sticks over the bird bath to only allow birds to drink, not bathe, may be a good idea in this situation. Many birds will eat snow in winter to get water.

Most bluebirds move out of the northernmost areas of their range in winter. Even ones that may linger eventually move on, once their berry sources are depleted or ice-covered. For bluebirds, and many birds, there is a trade-off of staying more north in order to be first to claim prime breeding territories, yet risking survival due to bad weather. Some of these tips may help them survive and you feel you're helping them. Bluebirds are truly beloved.
