SIB “Bird of the Week” – Northern Parula

Northern Parula – Setophaga americana
Length:  4.5″; Wingspan: 7″; Weight: 0.3 oz.

Northern Parulas are tiny, dainty birds and one of North America’s smallest wood-warblers.  These birds are very active and beautiful warblers that are sometimes hard to see because they love to forage in the dense foliage of mid to upper tree canopies.  Most birders hear their familiar rising buzzy trill with a final sharp note long before they get a glimpse of this warbler.

On Seabrook Island we are fortunate to have these birds from late March through summer months while they are breeding.  Once you are familiar with their sound you will be amazed as you drive/walk around our island how many Northern Parulas make Seabrook their home.  In fact, we’ve been hearing them often as we golf both Crooked Oaks and Ocean Winds.

These small birds are only 4.5” in length and weigh only 0.3 ounces. Male Parulas are mainly blue-gray above with two conspicuous white wing-bars and a partial white eye-ring.  They have a light greenish-yellow triangular patch on back; throat and yellow breast and white belly.  Adult males have chestnut and black bands across breast.  Female colors are similar to males but duller and generally lack breast bands. First-year (<1 yr old) birds are similar to females but more greenish on upper parts.

Northern Parulas are mainly insectivorous.  They feed mainly on spiders, damselflies, grasshoppers, beetles, caterpillars, flies, wasps, and ants.  Regardless of season, caterpillars and spiders are consumed most often.  During the winter, the Northern Parula consumes more beetles and occasionally forages on berries, seeds, and nectar.

They are a monogamous species.  Their habitat during breeding is along swamps, ponds or lakes in humid woodlands where they can nest in Old Man’s Beard lichen or Spanish moss.  Pairs often return to same nesting site year after year.  Males sing during migration and throughout nesting season, even when feeding young.  Nestlings are fed mainly by females and the average rate of feeding: 1 trip/13.6 min. Over a 6-hour period, one female carried food 19 times.  When they are not breeding you might find Northern Parulas in pastures; dry or wet forests; and agricultural fields or plantations.

A group of warblers has many collective nouns, including a “bouquet”, “confusion”, “fall”, and “wrench” of warblers.

Our National Bird: Bald Eagle?

Bald Eagle – C Moore

I always enjoy seeing a Bald Eagle on any of our bird walks. I’ve learned that juveniles don’t have the signature white head and tail shown on adults. As we approach July 4th, I remembered the Bald Eagle was not Ben Franklin’s first choice. Google to the rescue.

One of the many articles I found was from The National Wildlife Federation – November 2007 :

Nations often adopt animals as symbols: England has its lion, India its peacock. On the afternoon of July 4, 1776, just after the signing of the Declaration of Independence, the Continental Congress appointed a committee made up of Thomas Jefferson, John Adams and Benjamin Franklin to select a design for an official national seal.

The three patriots had different ideas and none of them included the bald eagle. They finally agreed on a drawing of the woman Liberty holding a shield to represent the states. But the members of Congress weren’t inspired by the design and they consulted with William Barton, a Philadelphia artist who produced a new design that included a golden eagle.


Because the golden eagle also flew over European nations, however, the federal lawmakers specified that the bird in the seal should be an American bald eagle. On June 20, 1782, they approved the design that we recognize today.


At the time, the new nation was still at war with England, and the fierce-looking bird seemed to be an appropriate emblem. But from the start, the eagle was a controversial choice. Franklin scowled at it. “For my part,” he declared, “I wish the eagle had not been chosen as the representative of this country. He is a bird of bad moral character; he does not get his living honestly. You may have seen him perched in some dead tree where, too lazy to fish for himself, he watches the labor of the fishing hawk and, when that diligent bird has at length taken a fish and is bearing it to his nest for his young ones, the bald eagle pursues him and takes the fish. With all this injustice, he is never in good case.”


Some people have since questioned whether the eagle would have been chosen to adorn the seal had the nation not been at war. A year after the Treaty of Paris ended the conflict with Great Britain, Franklin argued that the turkey would have been a more appropriate symbol. “A much more respectable bird and a true native of America,” he pointed out. Franklin conceded that the turkey was “a little vain and silly,” but maintained that it was nevertheless a “bird of courage” that “would not hesitate to attack a grenadier of the British guards who should presume to invade his farm yard with a red coat on.” Congress was not convinced, however. The eagle remained our national symbol.


In truth, both the turkey and the bald eagle are native to the Americas. But if the issue is a bird that represents our nation, Americans can’t really lay exclusive claim to either species, since both traditionally ranged in Canada and Mexico as well.

In 2017 Charley Moore created an article on Bald Eagles for the Seabrook Island Birders’ “Bird of the Week.” Although the nest he mentions is no longer present, the rest of the article is a great resource to learn more about our national bird.

The 2022 eaglets would have fledged but if anyone knows where our resident Bald Eagles built in 2022, let us know. We still see Bald Eagles flying over Seabrook Island so we know they are still in the area.

Least Terns: Threatened birds return to Morris Island to nest

Those of us on Seabrook Island were disappointed this year when the Least Terns nests were washed over by the unusually high king tides in May. An article in the Post and Courier on July 1 indicates others in the Low Country are having better luck:

MORRIS ISLAND — Squeezed off of many beaches by rising sea levels on one side and development on the other, least terns often nest on gravel rooftops near the South Carolina coast.

But about 40 pairs of the threatened species showed up this year on the beach at Morris Island.

Hints for Feeding Hummingbirds

It’s great to learn something new, especially when it saves you time and effort. Recently I was listening to the podcast Talkin Birds. Mike O’Connor, the owner of Birdwatchers General Store on Cape Cod, contributes weekly in a segment called “Let’s Ask Mike”. A couple weeks ago his topic was on feeding the hummingbirds. I was a little disappointed because I thought that this was pretty common knowledge for anyone who had hummingbird feeders.

As it turns out, I was not as clever as I thought. I have always boiled four cups of water and then stirred in one cup of sugar to make my hummingbird nectar. After it cooled, I filled my feeder with the sugar-water and stored the remainder in the refrigerator. According to Mike O’Connor there is no need to boil the water. Simply place a ratio of 4 to 1 – tap water to sugar -for whatever amount you need into a glass jar, shake until dissolved and place into your clean feeder. This method was corroborated by a Google search and verified by Judy Morr who told me that they never boiled their water. 🤷‍♀️ This saves me time, a used pot, and a jar taking up space in my already crowded refrigerator!

So, while we are on the subject, here is some additional hummingbird feeder protocol.

NEVER USE SUGAR SUBSTITUTES IN YOUR NECTAR.
Never use organic sugar, stevia, aspartame, brown sugar, coconut sugar, demerara sugar, agave, honey, corn syrup, etc. to make the nectar. White granulated sugar is only sucrose which is what is found in flower nectar. The added minerals found in other unrefined sugars are a better choice for humans, but might have an unwanted affect on the hummers. Luckily the store brand white sugar is always available and very inexpensive. No red coloring is needed as most hummingbird feeders includes a red part. If your feeder is not red, simply add on a red ribbon or any other red object.

KEEP YOUR FEEDER CLEAN.
This is critical, especially with our long, hot, and humid summers. With our temperatures above 90° we should be replacing the nectar daily, but at least every other day. At 90° it takes very little time for the water to ferment and then spoil. High temperatures will cause mold and bacteria to grow quickly in the water and this is toxic to the birds. If you have ever left your sugar water out
too long, you know how time consuming it is to clean the mold out of the corners and holes of the feeder. If you are changing the water every couple days, that type of cleaning won’t be necessary. If there is no mold, you should only need to rinse it well with hot water. Do not use soap. If your feeder does need disinfecting, use a 2 to 1 part water and vinegar mixture.

Also, there is no need for a large jar feeder or the feeders with more than a few ports filled to the brim with sugar water. Hummingbird tongues are very long and can reach far into the feeder. Keeping the level of nectar low might also deter bees and wasps. If you are changing the water frequently you should only need a small amount of nectar. You can make one cup (¼ cup of sugar) or half a cup (2 tablespoons of sugar) of nectar and have more than enough for the next day or two. Because there are so many people put out hummingbird feeders now, you will probably not see more than a couple hummingbirds feeding at the same time. In fact, you will notice that hummingbirds are pretty territorial with regards to their feeding space. The exception might be at the end of the summer when the babies have fledged and they need the additional fuel to power their upcoming migration.

WATCH FOR RISKS AROUND FEEDER
Hummingbirds are very fast, but very small. Make sure that the area around their feeder is free from ants, bees, and wasps. Even though the insects are probably more interested in the nectar itself, the wasps or bees could attack the hummingbird if they felt threatened and the sting would be fatal. Praying Mantises are fun to look at and will not harm humans, but they are deadly predators to a hummingbird. They don’t seem to be prolific on Seabrook Island, but if you see one near your hummingbird feeder it would be wise to relocate it. Additionally, watch for and clear out any spider webs around the feeders. Hummingbirds will actually use pieces of webs in their nests and might even try to pick out caught insects from webs. Unfortunately, getting ensnared in a web when approaching the feeder could be fatal to the bird. The stretchy sticky strands of the web could quickly entangle a struggling bird.

Finally, if it’s possible, keep your hummingbird feeders up year round. Whether our winter visitors are year round residents or migrants passing through, we can’t be sure, but with fewer flowers available, it would be important to have a fuel source for the winter hummingbirds. And, what a treat to see them during the winter months.

A final FYI, the only hummingbird that we expect to see on Seabrook Island, and more specifically east of the Mississippi, is the Ruby-throated Hummingbird. In most other areas they arrive in April and have departed for Central America by the first of October.

SIB “Bird of the Week” – Little Blue Heron

Little Blue Heron – Egretta caerulea
Length: 22-29”; Wingspan: 40”
 It’s a Little Blue Heron in what is called “first year” plumage.

Molting Little Blue Heron - Bob Hider
Molting Little Blue Heron – Bob Hider

When a Little Blue is immature (i.e., during the year in which it is born), it is totally white. Until a birder has mastered the characteristics of our local white egrets, it is easy to confuse the Little Blue with one of those waders. In its second spring, it begins to molt into its slate blue coloration, and, during that change, it appears mottled as the picture shows. By the end of the summer, it will have its more typical warm purplish-brown head and neck and otherwise dark gray-blue body. The two characteristics that it does maintain are its bluish green legs and black-tipped bluish bill.

The Little Blue Heron is common on Seabrook. It inhabits both fresh water ponds and salt or brackish water wetlands. It’s not unusual to find one standing among the reeds on the edge of Palmetto Lake searching for a meal. It can also be found on a dock, staring intently at the marsh below. As an adult, it tends to be solitary as it forages for small fish, crustaceans, frogs and aquatic insects. It stands quite still often with its bill pointed downward waiting patiently for its prey. For this reason, they can be difficult to spot.

In contrast, the pure white immature Little Blue Herons are often found feeding with groups of egrets and other herons which probably protects them somewhat. Eight were counted simultaneously on a Seabrook dock and in the nearby marsh this spring. When observed with such a group, their slow-moving behavior distinguishes them from the more active egrets even though they are very similar in size to the Snowy Egret.

Little Blue Herons are gregarious breeders, nesting in bushes over or near water. During the spring and early summer, they are part of the flocks on Jenkins Point along with the ibises and egrets there. In its write-up on this species, Cornell Lab of Ornithology states, “A courting male points his bill straight upward, suddenly extending and retracting his neck. Little Blue Herons of both sexes, when courting, may occasionally grasp, pull, and shake branches while simultaneously erecting the feathers along their head, neck, and back…. Little Blue Herons and neighboring colonial birds have a pronounced impact on their nesting habitat—stunting the growth of vegetation by harvesting nest material and sometimes killing trees outright by the accumulation of guano.”  This is true on Jenkins Point.

Here are more pictures of Little Blue Herons in their full immature and adult plumages.

Did you know: What is the developmental timeline from egg to fledge?

As we watch the rookery on the golf course and also see those Eastern Bluebirds growing on the bluebird trail, we note these birds “grow up” at different rates.

The time spent from egg production to fledgling varies by species.  Smaller birds often mature more quickly and may go from newly-hatched chicks to fledgling juveniles venturing out on their own in a couple of weeks or less.  Raptors or larger species, however, may stay in the nest under their parents’ care for several months.  Some examples:

SpeciesIncubationLeave nest or BranchingHatch to Fledge
Ruby-throated Hummingbird11 -16 daysN/A20 – 22 days
Eastern Bluebird12 – 14 daysN/A17 – 18 days
Green Heron19-21 daysN/A16 – 18 days
Laughing Gull22-27 daysFew days after hatching35 days
Great Egret23-26 days3 weeks6 – 7 weeks
Wilson Plover23 – 25 daysShortly after hatching21 days
Brown Pelican29 – 35 daysN/A77 – 84 days
Bald Eagle34 – 36 days9 – 10 weeks56 – 98 days
* N/A means the species goes directly from hatchling to fledgling

Sexual maturity can take even longer, with small birds ready to take their first mates in a year.

A baby Eastern Bluebird will weigh slightly more than its parents when it fledges at just 17 – 18 days.  As seen above, the eaglet takes longer to fledge but it will be nearly full grown at 9 weeks of age. They will add some weight as they develop their flight muscles after they leave the nest. Their wingspan will be as large or slightly larger than the adults at this time.

When a young eagle first leaves the nest, its wing and tail feathers are longer than those of an adult.  As an eagle matures, its wing and tail feathers become shorter and narrower with each successive molt.  The larger wings of a juvenile make it easier for the bird to catch an updraft or weak thermal and to fly slower and in tighter circles than an adult.  The down side of the larger wings and tail is that the juvenile rises slower, sinks faster, and cannot soar as far as the adult.  Adult Bald Eagles are able to flap their wings faster and fly at a greater speed than immature eagles, making them more efficient at chasing down live prey.

SIB “Bird of the Week” – Turkey Vulture vs. Black Vulture

Turkey Vulture vs. Black Vulture  –  Cathartes aura and Coragyps atratus
Turkey Vulture – Length: 26″;   Wingspan:  67″;  Weight:  4.0 lb
Black Vulture – Length:   25″;   Wingspan:  59″;  Weight:  4.4 lb

No, those are NOT buzzards; they are vultures. We have no buzzards in North America but we do have two types of vultures: the Turkey Vulture and the Black Vulture, commonly referred to as TVs and Blacks. Both are very big, very dark, and very ugly (to some) when seen on the ground. They have no feathers on their heads and dangerous looking beaks. These features are important to their life style. As you probably know from seeing them around road kill, they are carrion eaters. Their sharp beaks enable them to rip apart a carcass and the featherless heads allow them to forage deeply inside a dead animal yet avoid getting residue on their heads – not pretty but most practical.

Close up, the most obvious difference between these two vultures is the color of their heads. The Turkey Vulture has a bright red head while the Black’s is dark gray. On the wing, the TV seems to be soaring unsteadily, tipping from side to side with its wings in a V-shape. It uses very few wing beats as it glides along and the “fingers” at the ends of its wings are distinctive. From beneath, the TV’s wings in flight appear to be two-toned with black on the top edge and gray on the bottom.

In contrast, the Black is stubbier in shape with a shorter tail and thicker wings. It tends to flap its wings more and has less of a V shape when gliding than the TV. A definite identifier for the Black are the white “windows” at the ends of its wings. Watch for them as the bird flies overhead.

It is more likely that a birder will see a vulture in the sky than on the ground. They ride the thermals to reach heights which allow them to see great distances. Both are very strong fliers, often flying near one another, using their keen eyesight to spot carrion. The TV also has exceptional sense of smell which gives it an advantage in locating carcasses. The Black makes up for its disadvantage by watching the Turkey Vulture and following it when it descends.

There seem to be more Blacks than Turkey Vultures. In fact, the reverse is true in the U.S. but the very social nature of the Blacks means we see them in groups while the TV flies and may even eat alone.   One on one, the Black will lose out against the bigger TV. However, if both are at a carcass, a flock of Blacks can take over from the singular TV.

Neither the TV nor the Black actually builds a nest. They use hollowed trees or stumps, thickets, caves and even abandoned buildings to have their young. Once found, a pair may reuse the sight for several years.
