Did you know there are seven species of owl that can be seen in Tn? Can be seen, but not without some difficulty. The easiest to hear and locate are the Barred and the Eastern Screech Owl. Great- Horned owl would be the next easiest to see while the other year round resident, the Barn owl, is the most uncommon and difficult to find. A local birdwatcher recently discovered one and it may be the only one in Davidson Co. reported this calendar year. The other owls include Long-eared, Short-eared, and Northern Saw-whet

Now is the time when some owls in TN are likely beginning to court with actual breeding occurs in late winter.

Great Horned Owls are the earliest nesting species in Tennessee with courtship beginning in late fall or early winter. They use a variety of nest sites, including trees, rock-bluffs, buildings, and sometimes the ground. They often put nests in hollows of broken-off tree trunks and sometimes use the nests of other bird species, like crows. Nest height ranges from 30 to 50 feet above the ground.

This is the largest owl nesting in Tennessee and is easily identified by its large size, ear tufts and yellow eyes. It is a nocturnal bird, common and widespread across North America. Its call is a soft hooting, much more subdued than the animated call of the Barred Owl. Males and females are alike in their plumage but as with most birds of prey females are larger.

Eggs are usually laid in January. Females do most of the incubating, which lasts up to 35 days. A typical clutch size is two eggs with the possibility of up to five. Both adults feed the young and at 5 weeks old they leave the nest. The fledglings do not fly well until about 9 weeks old and will remain with the parents for up to 3 more months.

Barred Owl nest later than Great-horned with peak egg laying in early March. Barred owls prefer to nest in cavities in deciduous trees but occasionally will use open nests made by hawks, crows, or squirrels.

They will use nest boxes where cavities are limited. Nest heights range from 20 to 50 feet above the ground. Clutch size is typically 1-3 eggs and the female does most of the incubation which lasts up to around 33 days. Both parents feed the young and at about 5 weeks old climb out of the nest but not able to fly well until 6 weeks. The young will stay with the adults for about 3 months.

Screech Owls

The Eastern Screech-Owl is a small owl, about 8.5" in length (height), with feathered ear-tufts. Its wingspan is about 20” and weighs in at only about 6 oz. The eyes are yellow, and the bill is greenish. Male and female plumage is similar. As is the case with most birds of prey the female is larger, but the male's voice is lower-pitched.

Its song is a distinctive trill and descending whinny that does not sound like the typical hooting of its bigger relatives, the Barred and Great Horned owls. To hear the call you can go to the Tennessee Watchable Wildlife website, or to the Cornell Lab of Ornithology website allaboutbirds.org.

The Screech owl has two color-morphs, reddish-brown and gray. In Tennessee the red morph outnumbers the gray by almost two to one. No other North American owl has such distinctive plumage differences. It is found in urban as well as rural areas and readily nests in nest boxes. We don’t sell a lot of Screech owl boxes per year but several customers have had success attracting them. Like most owls, it is more often heard than seen. This small owl will feed on insects, earthworms, rodents, and even crayfish and songbirds.

The nesting phase of Screech owls begins in March with peak egg laying late March to early April. Clutch sizes are usually 3 to 4 eggs but may be as many 6. Nests are usually in cavities that are either natural, excavated by a woodpecker, or human-made nest boxes, including Wood Duck boxes. They add no nesting material to the nest cavity. The female does most of the incubating which lasts about 26 days. It then takes around 30 days, give or take a few, for the fledglings to leave the nest and then remain dependent on the parents for up to 3 months.

If you are a do-it-yourself person and need a winter project try building a Screech owl box. Follow this link and find instructions to build your own, as well as many other plans for wildlife structures.

The Yellow-bellied Sapsucker and Wet Weather Bird feeding Help

Male

Female

This winter if you see a woodpecker that doesn’t quite look like any of the usual woodpeckers you regularly see you probably have a Yellow-bellied Sapsucker. A little smaller than a Red-bellied Woodpecker at about 8 ½” in length , the Sapsucker gets its name from its telltale habit of creating evenly spaced holes around a tree trunk or large shrub to release sap to feed on. The drilling does not kill the tree because the tree is not being girdled. Note: I have a Viburnum at my home that is 25 years old and riddled with Sapsucker holes. It leafs out and blooms every year.

The Sapsucker is a fairly common winter visitor across the state of TN found in residential yards as well as in woodlands. It is a handsome bird known for its red forecrown on a black and white head; the chin and throat are red on male, white on the female. The back is blackish with a varying pattern, with a white rump and large white wing patch. The underparts of the bird are yellowish, paler on a female. They clearly stand out among our usual woodpeckers.

Suet is a good choice to attract Sapsuckers, although I do see them going to fine sunflower hearts presented in a finch feeder. I use mainly peanut butter suet and see sapsuckers feed there all winter. Video Other things to try are fruit and nectar. Nectar can be offered in a standard hummingbird feeder and sapsuckers may find this a suitable supplement to tree sap. After all, many of you see Downy woodpeckers feeding on hummingbird feeders all summer long. Sapsuckers have the same long tongue that can wick nectar out of the feeder. Sapsuckers generally leave this area by mid-April and head back north to their breeding areas. Look for this bird and let us know if you see one.

Notable sightings in TN this past week include Pacific Loon at Percy Priest Lake and a

Black-chinned Hummingbird in McMinn County, TN. I spent a day at Centerhill Lake recently and saw at least a dozen Common Loons.

Winter tends to be our wet weather time of the year. Soaking rains can present a number of problems at feeders, especially feeders that contain shelled offerings like sunflower hearts, Premium Blend, shelled peanuts, and suet. Everyone who’s fed birds for any length of time has encountered the awful experience of cleaning out a feeder full of wet, ruined seed. It’s really messy and it stinks, and your investment in the more expensive seeds is lost. Try protecting your investment with one of the many weather guards, or hanging squirrel baffles, available for a variety of feeders. Hanging Squirrel Baffles are just larger versions of weather guards thus offering optimum weather protection.

Through next Friday, Dec. 6

All Weather Guards and Hanging Squirrel Baffles are 20% Off.


Bird Bio: Black-crowned Night Heron

On recent visits to Centerhill Lake there have been some really good birdwatching opportunities. Sightings include Prothonotary Warbler, Barn Swallows, Purple Martins, Great blue Heron, Belted Kingfisher, Green Heron, Bald eagle, Red-tailed Hawk, Wood Thrush, and the bird we will focus on this week, the Black-crowned Night Heron.

Prothonotary Warbler

Green Heron

The Black-crowned Night Heron is a stocky, short legged bird most often seen in marshes, and along shorelines of rivers and lakes. They have a black back and cap which is in stark contrast to its gray wings and white underparts. Seen through binoculars you will see its red eyes. The legs are yellowish to yellow-green. During breeding you might be fortunate to see the long white head plumes on display. Their vocalization is a short flat “quok”.

Perhaps these herons are not seen as routinely as other species because they are mostly inactive during the day, often just sitting in a hunched over posture. It was in this posture that I first sighted the birds on a power line extending to the boat dock. They become active around dusk to feed, hunting for fish and other aquatic life.

During the breeding season both male and female take part in nest building, and interestingly, the male assumes some of the incubation duties and care for the young after hatching. A clutch usually consists of between 3 and 5 eggs.

Keep your eyes open and your binoculars handy. Wherever you find yourself recreating there will likely be some interesting birds.

Bird Bio: Hermit Thrush

Look for the elegant Hermit Thrush in brushy areas and understory of forest. I consistently see Hermit Thrush at Hidden Lakes State Park in the wooded part of the trail back near the trail that leads to the “dance floor” on the hilltop. There is quite a bit of bush honeysuckle and vine honeysuckle in this area which provides a lot of food and dense cover.

The Hermit Thrush is mostly a buffy brown but has bold spots on the breast. It is distinguished from other thrushes by its reddish colored tail and distinctive white eye ring. If you see one look for its habit of flicking wings and tail pumping (click here for a quick video). This is the only thrush normally seen in the winter in North America. This is not a bird you can set out to attract. On occasion I have seen Hermit Thrush below my birdfeeders during wintery weather, perhaps picking up pieces of suet or bits of seed. Some customers have seen them attracted to live mealworms, too.


Those of you who truly love feeding birds understand how it enhances your life.

This Holiday Season consider giving the gift of birds to a youngster, friend or loved one needing an interest, or to someone you may know confined indoors.

The Wood Thrush Shop is offering a starter bird feeding kit for $39. The kit includes choice of hopper feeder, or Droll Yankee tube feeder, choice of Black-oil Sunflower, Safflower, or Woodland Blend 8# bag, and a Pocket Naturalist guide to Tennessee Birds.

These items regularly retail for $52.

Get someone started feeding birds and help them discover a whole new world right outside their door.

Choose between a hopper or tube style feeder, a bag of sunflower or safflower, and a Tennessee folding guide for $39.

Bird Bio: Fox Sparrow

Sparrows are a family of birds that the backyard birder tends to overlook. All sparrows seem to be lumped into the same vague description of “little brown birds that mostly stay on the ground”. Sparrows, though, are a pretty diverse group. Yes, they have many similarities but upon closer inspection you can see just how beautiful and varied they are. The Annotated Checklist of Birds of Tennessee recognizes 26 species of sparrows, 10 of which breed here. Many are considered rare, to uncommon, to seasonal, with few as year round residents. This time of year we see with regularity Field Sparrow, Song Sparrow, Swamp Sparrow, White-throated Sparrow, White-crowned Sparrow, and Juncos are included in the family, too. This week we’re going to focus on the Fox Sparrow. Last weekend I was birding at Hidden Lakes State Park on McCrory Ln and really had fun looking for sparrows in the lower meadow area along the Harpeth River. I got several good looks at Fox Sparrows as they darted from cover to cover feeding on native plant seeds.

Song Sparrow

The Fox Sparrow is a large sparrow measuring up to about 7”, which is just a little smaller than a Northern Cardinal. It is recognized for its heavily streaked rusty colored breast, and a rufous, or orange-brown tail, which is more noticeable in flight. The rusty brown combined with gray around the neck gives it its foxy look. Its song is described by Peterson’s Field Guide as brilliant and musical; a varied arrangement of short clear notes and sliding whistles. Click on the picture above to hear their song and read more. Behaviorally it feeds similarly to the Eastern Towhee scratching with both feet on the ground while foraging. It is a very distinguishable hopping forward and back motion. Look for Fox Sparrows to appear on the ground below feeders during wintery, snowy weather. Millet is a food of particular interest to them. By April Fox Sparrows leave this part of the country to go back north to their breeding areas.
