Recent Bird News

The recent nearly 8” of snow we had certainly increased bird feeding activity to levels we are more familiar with. Many of you saw Purple Finch and Pine siskin, Red-winged Blackbirds, and lots of Juncos. Thanks to all of you who were patient with our freight difficulties and low level of seed inventory. It may interest you to know we sell in the neighborhood of 6,000 lbs of seed per week. So, when winter weather disrupts freight and the need for seed increases we can get into a bind. I’m happy to report we are well stocked and back to normal.

We have a customer in West Meade who has a “special visitor” coming to a suet feeder. This bird is not considered rare but more along the lines of uncommon. The bird is a female Baltimore Oriole and it is coming to suet. We always point out to people that suet is a great food source for wild birds and is the most likely food to appeal to a more unusual species, like this Oriole. It’s been visiting semi-regularly even before the winter storm. The Baltimore Oriole primarily passes through TN during its migration in the spring to areas more north of TN where they breed. March and April are the best months to see Orioles, the male with its bright orange plumage and black and white wings.

Every book I’ve picked up over the years about bird feeding strongly recommends putting out orange halves to attract Orioles but upon further research Orioles prefer ripe dark colored fruit. The darkest Mulberries, the reddest cherries, and the deepest purple grapes are on their preferred fruits list, and will ignore green grapes and yellow cherries. So, this spring I will be presenting some cherries and grapes rather than the oranges that have not worked for me. Orioles will visit hummingbird feeders, too, as they have a similar specialized tongue for extracting nectar and juices from fruit.

Another very interesting visitor to a feeding station in the Brentwood area, and more unusual than the Oriole, is a Black headed Grosbeak.

The BHG resides primarily west of the Mississippi River from Central America to as far north as southern Alberta and British Columbia during the breeding season. The lone bird was coming to a platform feeder for seed, sunflower and millet, I believe. Reported sightings of this species are few making it a rare bird.

The most unusual news to share, though, is a confirmed active House Finch nest with babies. The customer reported a nest and eggs in early January in a typical House Finch nest location, their front door on a wreath. I reached out to them to find out if the babies had developed and grown enough to fledge but have not heard yet. I will share that news in the coming weeks. I cannot remember ever hearing of an active songbird nest in January.

Wood Thrush Notes: Native plants & Hummingbirds

Consider Native Plants

Many of you, including myself, experienced loss, or at least significant damage, to plants with the rapid temperature drop and freezing weather this winter. Most leafy evergreens really took a hit as wind and subzero temperatures caused leaves to turn brown and drop off. This does not mean the plants are dead, and one will have to wait to see if new growth emerges. But if you are planning on replacing some plants, I suggest choosing native plants.

Habitat loss is the number one reason for species decline as development continues to reduce land once occupied and utilized by insects, birds, and animals. Vast amounts of natural habitat are now becoming islands of habitat. Scientific studies confirm wildlife thrives in greater numbers where gardens are planted with native plants that provide seeds, nuts, fruit and produce valuable blossoms for nectar. Spring is nearly here and gardening will be on your mind. Give some thought to replacing those cultivated varieties of plants with natives and the rewards will be great. Aside from attracting birds that do not visit feeders native plants require less watering, attract pollinators from bees to butterflies, do not require pesticides, survive tough TN growing conditions, and they are beautiful. A great local source and recognized as one of the leading native plant nurseries in the U.S. is GroWild in Fairview, TN. www.growildinc.com

The Perennial Plant Society of Middle Tennessee is another good resource for plants and information. They will be having their annual plant sale on April 8th from 9 am to noon at the Nashville fairgrounds. Visit their website for more information. www.ppsmtn.org

Another organization you may want to be familiar with is Habitat Connection. Habitat Connection is a non-profit organization made up of a small group of people sharing a passionate interest in improving habitat on a small scale, namely our yards. Their goal is to improve the health of our ecosystem in yards and to create connectivity for birds, wildlife, and us. They can help you implement a plan specifically for your yard.

When are the hummingbirds coming?

It’s a question we hear a lot in the store beginning in February. We are just 2 ½ weeks away from some of the first sightings of Ruby-throated hummingbirds. Ruby-throated hummingbirds (RTH) are in fact moving this way as they do every year at this time. Male RTH’s begin arriving along the Gulf Coast in February preceding females by as much as a week to ten days. There are no exact arrival times but year to year observations suggest they are quite punctual. For 30 years I’ve noted the first siting of a hummingbird at my home. It’s never been earlier than April 4 and never later than April 11. And it has always been an adult male. It's often thought if it's warmer here they will arrive sooner. Perhaps warmer weather will aid them in their migration but it doesn’t mean they will get here that much earlier. After all they do not know it’s warmer here. Migration is triggered by the lengthening of daylight hours, and instinctively they have made this journey from Central and South America for thousands of years. The very earliest hummingbirds may be seen in the last week of March with the bulk of them arriving or passing through from mid-April to mid-May. Many of these birds will continue to their breeding areas as far north as Canada and all areas in between while some settle here for the summer.

The other question we answer regarding hummingbirds is “when should I put a feeder out?” You may put one out as early as the last week of March but do not expect late summer-like activity. Feeders are of assistance but certainly not like they are prior to fall migration. This year may be different in that plants that provide blossoms for nectar may be in short supply from winter damage. We shall see.

Great Blue Heron Rookery

While canoeing on the Harpeth River last weekend I pulled onto a gravel bar to stretch my legs. As I looked around, I noticed in the distance a large tree with what looked like large clumps of mistletoe growing in the top 3rd of the tree. A moment later a very large bird approached and landed near one of the large clumps which I soon realized were Great Blue Heron nests. Through closer observation with binoculars I could see there were already two more GB Herons positioned alongside other nests. I had located a rookery which is an area where Great Blue Herons nest in groups, or colonies.

Great Blue Herons nest mainly in trees, but will also nest on the ground, on bushes, in mangroves, and on structures such as duck blinds, channel markers, or artificial nest platforms. As early as late January males arrive at the colony and begin to settle on nest sites; from there, they court passing females. Colonies can consist of 500 or more individual nests, with multiple nests per tree built 100 or more feet off the ground.

Male Great Blue Herons collect much of the nest material, gathering sticks from the ground and nearby trees, presenting them to the female. She weaves a platform and a saucer-shaped nest, lining it with softer materials like pine needles, moss, and dry grasses. Nest building can take from 3 days up to 2 weeks; the finished nest can range from a simple platform measuring 20 inches across to more elaborate structures used over multiple years, reaching 4 feet across and nearly 3.5 feet deep.

Peak egg laying is around mid-March her in TN. A typical clutch size is 2-6 bluish eggs, and incubation takes up to 29 days. The fledgling period is a minimum of about 49 days and can be as much as 81. Individuals usually do not nest until at least 2 years old.

Great Blue Heron rookeries are not difficult to find, especially this time of year with no leaves to obstruct views of nests. They are common year-round residents and can be found along, or near any body of water.

Spring Birding Class

Richard Connors will be offering his bird identification class “Birding by Ear, Bird Study by Sight and Sound” at Radnor Lake again this spring.

The class will emphasize birding by ear, and is designed for beginners and intermediates, and will be a good opportunity for anyone wishing to brush up and study our local birds. Classroom sessions will be combined with guided bird walks taking advantage of the fact that Radnor Lake is the premier place to see, hear, and study birds in the Nashville area. Our local birds will be covered, and of special interest will be the wood warblers, the elusive and colorful spring migrants that Radnor is so famous for. Through this class you will increase your proficiency in bird identification, learn how to enhance your yard to attract birds, learn what bird resources are available, and learn where to go in our area to look for birds.

The 5-week class will meet Tuesdays April 4, 11, 18, 25, and May 2. The first class meets on April 4th, 10AM – 12:00 PM in the visitor center meeting room, Radnor Lake State Natural Area, 1160 Otter Creek Rd., Nashville.

Morning bird walks start April 14 at 7:30 AM, followed by classroom sessions starting at 10 AM. There is a $75 fee for the class, with a portion of the fee going to Friends of Radnor Lake.

Contact Richard to register for the class: Rconnorsphoto@aol.com, call or text 615 330-7142. For more info visit Richards info page here. https://pbase.com/rconnorsnaturephoto/spring_bird_class_2023

Wood Thrush Notes

Yellow Cardinal in TN

A backyard feeding station in Harriman, TN, in Roane County has quite an unusual visitor.  They have a yellow Cardinal visiting on a regular basis.  Yellow Northern Cardinals have been seen in at least 4 different states the last ten years but remain a rarity.  What causes a bird that is normally red to be yellow?  Basically, the red, orange, and yellow colors in birds’ feathers are created with carotenoid pigments derived from the foods they eat. In the male Northern Cardinal, yellow pigments from the diet apparently are converted to red by a specific enzyme. In a very rare genetic mutation, probably affecting fewer than one in a million cardinals, that enzyme is lacking, so the conversion to red doesn’t occur and the feathers are bright yellow instead. 

Get Ready Now for Nesting Season

Just two weeks from now we will say hello to February, perhaps our coldest and potentially snowiest month.  But you can always count on a few days that warm to the 60’s and suddenly bird activity ramps up.  Some birds will begin singing and some, like the Carolina wren, may actually begin nest building. 

The Carolina wren, as you have probably seen, chooses some pretty odd locations to build a nest and often times in  places humans find annoying, like in a gas grill, or canoe, for example.  They often choose locations like covered porches, garages, and garden sheds.  Every spring we receive several calls from people who suddenly find themselves with a bird nest full of babies in a troublesome location.  If you have experienced this scenario get ahead of the game and block access to these locations as soon as possible. 

And now is a very good time to review the nest box successes and failures you had last year and make adjustments if necessary.  If a nest box has been in the same location a couple of years with no activity go ahead and try a new location.  Move it soon.

Clean out old nests now if you haven’t already before birds begin new nest building.  Of course, birds will build on top of old nests but that can be a problem as insects like ants will find the old decaying nest attractive.  I have saved baby birds from certain death as the ants were beginning to eat them alive.

If you’ve never offered a Bluebird box consider putting one up in the month of February.  Even though the majority of Bluebirds won’t begin nesting until April they will do a lot of surveying of potential places to nest Feb. thru March.

National Bird feeding Month and the GBBC

February is National Bird Feeding Month and the Great Backyard Bird Count.  Many of you look forward to the count and sharing your data to help bird experts better understand the distribution and relative numbers of the different species of feeder birds. More info on the GBBC next week

Hummingbird sighted last week

Just last week, on Thanksgiving Day, a hummingbird was spotted at a feeder in western Davidson Co. on the Cheatam Co border. The homeowner was outside taking a break from cooking when the bird was seen going to a feeder she keeps out all winter. The homeowner, a long time Warner Parks employee who has a hummingbird banding license immediately prepared one of her traps to put the feeder in. It didn’t take long for the tiny visitor to enter the trap for the nectar. The bird was captured, measured and weighed, banded, then released. With the data compiled there was reason to believe this bird is an Allen’s hummingbird. It was in fact determined to be a young female but because an Allen’s can be so similar to another species, the Rufous hummingbird, the jury is still out.

Other bird banders are discussing the details and data to make the ID official. Regardless, it is very interesting to know we have small numbers of hummingbirds that spend, at least temporarily, the fall and winter with us. It doesn’t mean you should put your humming feeder out but certainly you can and there is a chance you may see one of these western U.S. hummingbirds. I’ve been trying for many years with no success.
