End of Summer-Early Fall Notes

We have received more than a few calls recently regarding the very noticeable slowdown at feeders in recent weeks. The degree of slowdown may vary each year but without a doubt September and October are the two slowest bird feeding months of the year. My 28 years of tracking sales data backs this statement up. We always sell far less seed and suet during these two months. So why does it slow down?

There are two reasons why feeder activity slows down at this time. Feeder activity is at peak level during the breeding-nesting season, between the months of March and July. We get used to the abundance of birds visiting our feeders and many of us are filling feeders frequently, every other day if not more. While nesting and raising young birds take full advantage, but do not rely on our feeders. Raising young takes a tremendous amount of energy and rather than having to forage for food at greater distances they will increase their visits to feeders exponentially, thereby staying closer to the nest and their valuable offspring. And many of our feeder birds will nest twice per breeding season. So, the first reason for the slowdown is the breeding season for our year round and summer resident birds has long been over, for at least a month and a half. The need for “extra” food has passed.

The second reason is by the end of summer and beginning of fall plants are producing seeds, nuts, and fruit. Beneficial insects chocked with protein are still very much available. Instinctually, birds cannot pass up the abundance of natural foods and variety now available. Therefore, the feeders that were important to them in the spring and summer become less important now. With no young to attend to they have little to do but feed on what nature is offering and to cache food for later use. Sure, you will still get birds visiting your feeders but not like during the breeding season. This would also explain why we rarely see Rose-breasted Grosbeaks at our feeders in the fall on their return trip to the tropics, when they are such prominent feeder birds in spring. Natural food is everywhere and unless something occurs to prevent food production, like a drought, birds will gravitate to it before going to feeders.

As much as the business owner side of me hates to see the slowdown I also appreciate the opportunity to point out birds do not rely on or survive on our feeders, as many people mistakenly believe.

Experience says by mid-November, or earlier if there are a couple of good frosts, you will see a return to busy feeders. So, don’t think something has happened to our birds. It really is just birds being wild animals acting on thousands of years of instinct. They will return to your feeders. By the way, this slowdown is a great opportunity to give your feeders a thorough cleaning.

Molting

Have you been finding feathers around your yard, or maybe seen some really funky looking Cardinals or Bluejays recently? Seeing Cardinals or Jays with an alarming lack of feathers on their heads is quite common after the breeding season.

Molting is the process by which birds lose damaged or worn out feathers with new ones providing them not only with healthy new feathers but often a new look to their plumage in the form of new colors or patterns that may indicate a bird’s age, sex, or season of the year.  Feathers are comparable to our hair or nails made from the same basic ingredient, keratin.  

Molt is not a “one size fits all” occurrence.  There is great variation by species and even by individual from year to year.  While molt is associated with this time of year any time a bird loses a feather a new one will immediately begin to grow in its place. 

Occasionally, Cardinals and Bluejays will lose all their head feathers in a short amount of time and while it takes a while for the new ones to grow in the result will be a bald bird.  I’ve seen a number of male Cardinals recently that were in between bald and the emergence of new feathers.  They look rather odd as their heads under the feathers are dark gray to black.

Hummingbirds Getting Plump

I’ve seen some chubby hummers at the feeders lately as they continue to feed heavily and store fat for their long journey.  There’s plenty of time remaining to enjoy hummingbirds as they prepare for their return to Central and South America.  While you may have already seen a reduction in numbers of hummers at your feeders keep in mind Ruby-throated hummingbirds continue to head south from as far as Canada.  These very birds may show up at your feeders at some point weeks from now so keep the fresh nectar coming and your feeders clean.  Earlier in September I was in Maine and had several sightings of hummingbirds.  Isn’t it amazing when you consider the distance traveled by these little dynamos?

Fall Slowdown and Fall Hummers

Fall Slowdown

Many of you have already noticed a slow down at your feeders. Sometimes it can be abrupt and dramatic. You may even notice some species become practically non-existent. Bird feeders in September and October are typically very quiet. This is surprising to some but actually normal and understandable. With the conclusion of the breeding season birds are now in less need of the quick, easy food source at your feeders. While raising their young during the months of March through July birds expend tremendous amounts of energy raising young and will take great advantage of backyard feeders. We sell more seed and suet during those months than we do in winter.

Young birds are mostly independent now and the lives of adult birds are at a much more leisurely pace. In addition nature is producing an abundance of food at this time. Not only are insects still plentiful but every tree, shrub, weed, and wildflower are producing seeds, nuts, and fruit. There is literally food for birds everywhere. It is a great example of the fact that birds do not rely on our feeders but simply take advantage of them in times of more demand for food. So, don’t worry that you are not seeing many birds around the feeders right now. It is totally normal. About the time we get the first frost or two, you will begin to see a return of your favorite birds to feeders. I don’t know about you but a good frost sounds good right about now.

By the time October arrives you will begin to see a few of our winter visitors, like Junco’s, White-throated sparrows, Yellow-bellied sapsuckers, Kinglets, and hopefully, Purple Finch, Pine Siskin, and Red-breasted Nuthatch. Although, with the Pine siskin issues (salmonella) we had last winter I would prefer they not visit us this winter.

Ruby-throated Hummingbirds will continue to be present through October though their numbers will be fewer with each week that passes. The peak of hummer feeding activity has likely passed so I reduce the numbers of feeders I offer by a few. As mid-October arrives I will continue to offer at least two feeders. And because there is always a remote possibility of a western hummingbird showing up I will leave one feeder out beyond Thanksgiving.

Rare Mexican Violetear

Each year a few people around the mid-state are pleasantly surprised to discover a hummingbird investigating a feeder that may have been inadvertently left out with no nectar. Two customers within 3 miles of The Wood Thrush Shop experienced Rufous hummingbirds last fall. Western hummingbirds that have regularly been seen in TN include Rufous, Anna’s, and Black-chinned. Last year a Mexican Violetear was trapped and banded in Montgomery Co. For more information about wintering hummingbirds you may want to visit southeastavianresearch.org

Fall Migration Notes

Fall Migration is underway and while your birdfeeders will slow down as we approach October birdwatching will only get more interesting.  Have your binoculars with you and ready because warblers are pouring through middle Tennessee stopping to feed in the early mornings on insects and berries.  Mornings are the best time to see lots of different species of warblers.  And mornings after a storm tend to be even better.  Make time to visit one of the many great local birdwatching areas this fall to see some of them.  For information about great places to birdwatch click on the links below…

• Tennessee Birding Trails is a great website for locating trails for specific types of birding.

• Tennessee Birding Facebook group has an active community of birders who post often.

• Tennessee Ornithological Society (TOS) Nashville Chapter is having their Radnor Lake Wed morning bird walks September 19th and continue each Wednesday through October 10th. Please meet in the west Parking lot outside the Visitor’s Center at 7:30am. Come rain or shine. With the exception of ongoing downpours or thunderstorms.

• TN-BIRD email list is a free list that allows you to get updates of bird sighting from other birders in the area. to receive emails simply click on “find and join” at the top right of the tn-bird page, search for list name tn-bird, and follow the instructions on signing up your email.

One of the more interesting, easy, and fun things to see in the fall is the migration of Chimney Swifts and Common Nighthawks. In the evenings, particularly in areas where there is outdoor lighting, like high school football games and shopping malls, Common Nighthawks gather and feed on insects. Downtown areas tend to be very productive areas to see both.

The Common Nighthawk, a member of the Goatsuckers family, measures around 9 1/2 “in length. They are gray-brown with slim, long wings that have a distinctive white bar near the tips. They are most active at night but can be seen midday as well. They fly with long easy strokes but can quickly change direction and appear erratic as they catch flying insects. Male Nighthawks have a white throat and white band across a notched tail. Listen for the unusual “peent” call of the Nighthawk.

The Chimney Swift is a short swallowlike bird with long, slightly curved wings. Peterson’s field guide to Eastern Birds describes it as a “cigar with wings”. Always in motion, Swifts appear to continually fly never landing to rest and constantly “twitter”. They measure about 5 ½” in length and are uniformly grayish to brown. During migration Swifts have been known to roost together by the thousands in a single chimney. On more than a few occasions I have witnessed a “funnel” of swifts descending into the chimney of a downtown building while on my way to a Predators game. It is a fascinating sight.

And About Hummingbirds

We may see Ruby-throated hummingbirds well into October so keep your feeders out with fresh nectar as there may be several waves of hummingbirds still coming through TN on their return to Central and South America. The belief that feeders should be taken down to cause the birds to migrate is incorrect.  They will leave when they are ready whether there is a feeder present or not.  

Fall slow down at feeders

Many of you have already noticed a slow down at your feeders.  Sometimes it can be abrupt and dramatic.  You may even notice some species become practically non-existent.  Bird feeders in September and October are typically very quiet. This is surprising to some but actually normal and understandable.  With the conclusion of the breeding season birds are now in less need of a quick, easy food source... your feeders.  While raising their young during the months of March through July birds expend tremendous amounts of energy and will take great advantage of backyard feeders.  We sell more seed and suet during those months than we do in winter. 

Now young birds are independent and the lives of adult birds are at a much more leisurely pace.  On top of that nature is producing an abundance of food at this time.  Not only are insects still plentiful but every tree, shrub, weed, and wildflower has produced seeds, nuts, and fruit.  There is literally food for birds everywhere.  It is a great example of the fact that birds do not rely on our feeders but simply take advantage of them in times of more demand for food.  So, don’t worry that you are not seeing many birds around the feeders right now.  It is totally normal. About the time we get the first frost or two, you will begin to see a return of your favorite birds to feeders.  I don’t know about you but a good frost sounds good right about now. 

And you will begin to see our winter visitors, like Junco’s, White-throated sparrows, Yellow-bellied sapsuckers, Kinglets, and hopefully, Purple Finch, Pine Siskin, and Red-breasted Nuthatch.

Keep this in mind while you are buying your seed next time.  It’s advisable to buy smaller quantities until birds begin visiting with more frequency in November.  Remember, the more seed you end up storing in a container over the next two months the more chance there is of having a bug hatch.   

And while birds take a break from your feeders take time to give your feeders a thorough cleaning.  Warm soapy water, a brush, and a little effort are well worth the effort to provide a clean, healthy feeding environment for the birds. 

The Fall Slowdown

Have you noticed a lack of bird activity at your feeders in the last few weeks? It’s not anything you’ve done wrong and there is nothing wrong with the seed, it’s the seasonal transition that makes birds scarce at feeders. 
This time of year many of you will notice an abrupt and sometimes dramatic slowdown at your feeders.  You may even notice some species become practically non-existent.  Bird feeders in September and October are typically very quiet. This is normal and understandable.  With thebreeding season well behind them birds are now in less need of a quick, easy food source like your feeders.  While raising their young during the months March through July birds expend great energy and will take full advantage of backyard feeders.  We sell far more seed and suet during those months than we do even in winter.
Let’s not forget that the food birds get at your feeders is really only a supplement to their natural diet.  They do not become dependent on feeders.  Their frequency of visits to feeders is based largely on what is going on at that time in their life-cycle, seasonally and environmentally.  Your feeders are slow at this time of year because the breeding season is over and adults are not raising and feeding young, and practically all plants; weeds, wildflowers, shrubs, and trees, are producing seeds, nuts, and fruit.  Birds are taking advantage of the bounty nature is providing them.  Nature provides all this food in the fall to help wildlife get through the winter.  They are busily feeding and storing food for the months to come.  Will this be a tough winter? The birds likely know.
So don’t worry that you are not seeing many birds around the feeders right now.  It is totally normal. About the time we get the first frost or two you will begin to see a return of your favorite birds to feeders.  And be on the lookout for our winter birds like Purple finch, Pine siskin, Red-breasted nuthatch, and White-throated sparrow.
Although there are fewer everyday hummingbirds are still being seen.  Keep at least one feeder going and keep the nectar fresh.
