Update on Mysterious Bird Deaths

Last week we reported on the mysterious bird deaths taking place north of us and in Mid-Atlantic states. We have had no reported sightings of sick or dying birds from customers here in Nashville but we do recommend being vigilant. The TWRA has collected some specimens for testing and will make a statement next week regarding their findings. At this time the TWRA is recommending that feeders be taken down if you witness a dead or obviously sick bird. As reported last week the species most affected thus far have been Robins, Blue Jays, Common Grackle, and Starlings. I wish we could offer more detailed and definitive information; however, there is still much to be learned. As information from credible sources is gathered we will promptly share it with our customers.

Bald Cardinals

I have seen a number of Northern Cardinals recently that are partially to totally bald. They do look odd but it is normal and temporary. After the breeding season and usually beginning in mid-summer birds begin molting. Northern Cardinals and Blue jays often lose all of their head feathers at once rather than a little at a time like most other songbirds making their molt mostly unnoticeable. Sometimes the feather loss can be the result of a feather mite but this particular molt pattern for Cardinals and Jays is considered normal. If you see what appears to be a Cardinal with a black head grab some binoculars and look a little closer. It’s slightly disturbing at first but it does offer an interesting glimpse at the position of the ear which is below and back of the eye.

Update on Mysterious Bird Deaths

By now I’m sure many of you have heard the reports of birds inexplicably dying over the last several weeks in areas north of us including, Indiana, Kentucky, Ohio, Maryland, and Pennsylvania. Specimens of Blue Jays, Grackles, Starlings, and Robins (the most prevalently affected species) tested have turned up no clues as to what is killing them. Several illnesses have been ruled out including, Salmonella, several varieties of viruses, and Trichomonas parasites. Scientists are still scratching their heads trying to figure out the cause or causes. It has been recommended that people in the mentioned states take down feeders and birdbaths, or eliminate anything that contributes to birds congregating. There has been no known connection, however, to bird feeders and baths.

Because this issue has been widely reported on, sometimes irresponsibly, we wanted to offer some information to help make you aware and to be vigilant. If you encounter a sick or dead bird please contact us, or Ellington Agricultural Center. In the past week reports of dying birds have slowed and whatever has been affecting birds may be concluding. There have been no reports of dead birds with the specific symptoms of eyes crusted over and possible neurological issues in Tennessee. As always we recommend cleaning your feeders regularly. Make sure your backyard birds are being offered the best environment possible.

Here is a link to an article from Science Magazine that we found to be helpful on the subject.

Rare Bird Sighting

In Trousdale Co. this week a Roseate Spoonbill was reported and confirmed. The bird was seen in the company of Egrets. The Roseate Spoonbill is a pink bodied bird with red highlights, a long spatulate bill, and a grayish to green colored featherless head. Spoonbills feed in shallow water sweeping their bills from side to side. This bird is fairly common along the Gulf coast.

Tree Swallows and Bluebirds

Over the past ten years more and more people are reporting Tree Swallows using a nest box intended for Bluebirds. Tree Swallows are considered “competition” for the Bluebirds but typically that would be because there is only one box available. Such is the case when only one box present. In mid-TN there may be as many as 7 different songbirds interested in a Bluebird box; Chickadee, White-breasted Nuthatch, Tufted Titmouse, Carolina, and House Wren, Prothonotary Warbler, and the Tree Swallow. This is why we recommend offering a number of nest-box choices. To not only alleviate competition, but to give several species of birds an opportunity that these days are getting harder to come by because of loss, or disruption, to habitat.

The Tree Swallow is smaller than a Bluebird measuring about 5-6 inches in length. Male and female are a steely blue-green to nearly black above and pure white below. Females tend to be a little duller in color overall. In the sunlight the blue-green plumage is very perceptible. Their forked tail is not as pronounced as a Barn Swallow’s.

Like other swallows they are expert flyers acrobatically catching insects on the wing. They appear to enjoy flying.

Their habitat preferences are pretty diverse ranging from wetlands and marshy areas to meadows and woodlands near water. This bird is only here between late February and approximately mid-March as it migrates back to its winter grounds in Honduras, Nicaragua, and Costa Rica.

I recall reading accounts of Tree Swallows and Bluebirds using nest-boxes placed back to back on the same pole. I’ve never had a chance to test this but recently heard from a naturalist friend of mine experiencing this very thing. So, these two species are compatible enough to tolerate nesting in close proximity. If you have experienced Tree Swallows seemingly taking over one of your Bluebird boxes perhaps this is a chance for you to test this theory.

Hummingbirds, Box Turtles, and Hiring

,

As anticipated there has been a noticeable increase in hummingbird activity reported from quite a few customers this past week. Mid-June and mid-July are notable times when many hummingbirds will come off the nest which would translate to more hummingbirds being seen at feeders and around the yard visiting flowers. Lots of rainfall is contributing to wonderful results in our gardens producing an abundance of flowers. Often times these natural nectar sources are more attractive and more important than the sugar water in our feeders. We often tell people who are disappointed about not seeing hummers at their feeders that hummingbirds do not travel all the way from Central America for sugar water. They have all they need naturally and will come to the feeders with intensity when nesting concludes. Be patient. August and September are always the best hummer feeding months.

Most of us bird lovers appreciate many of the other creatures we encounter in our yards seasonally, from year to year. Most springs I encounter Box turtles methodically working their way through a flower bed, or some difficult terrain with obstacles. I wonder how they get anywhere as difficult as it seems for them to move. Many times I’ve discovered a female attempting to dig a hole with its hind legs with the intention of laying eggs. I’ve never encountered a baby Box turtle so it must be extremely rare to witness the emergence of the babies from the earth. Two days ago I encountered a beautifully marked female attempting to dig a nest hole with not much success before she moved along to a better spot. I rewarded her efforts with a couple of juicy earthworms. Enjoy the video. Females will lay between 3 and 8 eggs up to three times per year. This next bit of information is very interesting. Female Box turtles can store sperm from a single mating for up to 4 years and can produce a fertile clutch of eggs in each of those years without further mating.

Another Rare Bird Sighting in Nashville

In the past year, TN has seen quite a few rare birds pop up all around the state.

By now some of you have heard about the Green-tailed Towhee recently discovered in East Nashville. It’s not the first time this species has been seen here, however, nearly 60 years have passed since the last sighting.

This bird is typically a summer-breeding resident of New Mexico north to Montana, and west to the Sierras of California. Its non-breeding, winter range is from mid Texas down into Central America. The other interesting thing about where this bird has been seen is its habitat preference tends to be in areas of dense brush on mountainsides and high plateaus. Not exactly East Nashville habitat.

Keep the binoculars handy because clearly any one of us may have a rare visitor at any time.

Spring and Early Summer Hummingbirds

All of our summer resident Ruby-throated hummingbirds are here now and beginning, or well into, their first nesting of the season. Like Bluebirds they all don’t start nesting at the same time. There could be as much as a month difference in the first nesting phase of the earliest arrivals in March and April and the later arrivals as late as mid-May.

There have been a lot of concerns voiced by customers regarding hummingbirds this spring, more so than usual. “I usually have them by tax day”, or “I’ve only seen one weeks ago and none since”. The nesting phase is one of the reasons people usually see far fewer hummingbirds now as opposed to July through September. Hummingbird feeders are not in high demand at this time and will serve only for quick visits and a brief drink.

I’ll admit sightings of hummingbirds have been fewer based on personal experience and customer feedback; however, there can be a number of factors that would contribute to either seeing more or less hummingbirds during spring. Seeing fewer hummingbirds now can be viewed as a potentially good thing. It has been a cool spring with good amounts of rain meaning nectar producing plants are doing very well and hummingbirds do not see the feeders as necessary. In years past when we experienced early hot and dry conditions there was more early activity at feeders. Let’s see what happens when temperatures get into the 90’s next week with little rainfall. That may inspire a little more action at the feeders.

Perhaps the heavy rains and high winds we experienced in May and June last year resulted in a fair amount of washed out nests meaning numbers of offspring were affected. The fact is we just don’t know at this point if there are fewer hummingbirds this year compared to last.

When nesting is near conclusion in mid to latter July hummers begin visiting feeders with frequency and intensity to fatten up for the long migration back to Central and South America.

With that in mind keep fresh nectar in the feeder but do not fill to capacity. Small amounts are recommended now to decrease waste and major cleaning of feeders. In warmer weather nectar is only good for about 3 days. The hotter the environment the shorter the life span of the nectar.
