The Early Birds

On March 7th, my friend Susan Ott, was the first to notice the Montlake Bald Eagles behaving like they had eggs in their nest. (Thank you, Susan!) In the past, it has often been toward the end of March or early April before our local Bald Eagles appear to begin incubation. 

For example, last year, my first sighting of an eaglet in the Montlake nest (Thanks again to Susan!) was on May 21st. Working backwards, assuming 35 days of incubation, and expecting that the sighting happened in the ten days before the eaglet began to develop its second darker set of colored down, this implies that the egg containing this eaglet was probably laid during the first week of April in 2023. (Click Here to read the post from last year.)

If these assumptions are correct then Monty and Marsha have begun incubation almost a full month earlier this year. They also seem to be early as compared to our other resident Union Bay Bald Eagle pairs.

My friend Ronda has noted that Talia, the female in the nest on the old Talaris property on the north side of Union Bay, just began incubating around March 20th. This is just over a week earlier than her normal start date, which Ronda explained has been March 28th in the past.

On Thursday, March 21st, 2024, at the Broadmoor nest tree Albert was in the air, and excitedly lowering himself toward Eva, clearly hoping to once again initiate the egg-laying process.

Admittedly, because of the backlighting and obscuring foliage, it is hard to see what is happening, but I have no doubt about their reproductive behavior. In any case, as of March 21st, I had not seen either of them low in the nest, in an obvious incubating position.

On the other hand, every time I have checked on Monty and Marsha, after March 7th, one of the two has been in the nest.

This March 7th, 2024 photo shows one of the Montlake pair sitting in the nest with their wing tips pointing skyward. In years past, my friend Martin explained, that this positioning implies the eagle is lowering the middle portion of its wings on each side of the egg (or eggs) to help protect them. Because of the structure of their wings, when they do this their dark wing tips point upward. I have never seen this behavior except in the Spring during the time they are likely to be incubating eggs.

When the mate arrived in the tree it began cleaning its bill. In general, the female Bald Eagles are said to spend the majority of the time on the eggs but their mates come and take turns so the females can have a chance to find food and eat. Given that this eagle was wiping its bill on the branch it seems likely that it had just fed.

Curiously, this bill-wiping process, called feaking, has multiple benefits for birds. In addition to cleaning, researchers say it can help sharpen their bills and in some cases, the birds may be leaving a scent to attract potential mates. Click Here to read more about feaking. 

By the way, Monty and Marsha have a new nest this year. If you have visited them before the new nest will not be hard to find. It is in the closest possible tree to their old nest, i.e. just south of the totem pole on the southeast corner of Montlake Cut. Luckily, this year's nest seems to be built on a firmer foundation.

If you would like to see the new nest, visiting in the next week or two would be wise, before this Spring's leaves obscure the view.

Last year's nest was built on a simple, dual-branched, fork in a tree. The nest looked a lot like a pair of saddle bags draped over a horse's back, but without a cinch to hold it. 

When young eagles are preparing to fledge they bounce around a lot while practicing their liftoffs and landings. The stress on a nest increases dramatically. Multiple times over the years, Monty and Marsha's nests have fallen. Often their offspring have found themselves on the ground and unable to fly, which is a very dangerous situation for a young eagle. Sometimes, the nests have lasted a bit longer and the young have been able to fly to safety when the nest fell. (Click Here to read what happened with last year's eaglet and nest.)

This two-dimensional photo does not do a great job of showing the three-dimensional nature of the branches supporting the new nest. However, as they were building the nest the fork in the new tree looked more like an upturned hand, with fingers spread, rather than a peace symbol like the fork in the old tree.

Even while incubating appears to be underway, the eagles still occasionally apply finishing touches to the new nest.

Hopefully, the new nest stays in the tree, the eggs hatch and the parents provide a bountiful supply of food for their young. If everything goes according to plan their next set of young might leave the nest before the end of June. (Mid-July has been more typical in the past.)

It will be fun to see if the young from this nest are visible sooner than the young in the Talaris and Broadmoor Bald Eagle nests i.e., Will Monty and Marsha's young be the early birds this year?

Based on Susan's observation I am thinking the earliest hatch date is probably around April 11th. It will then take some time for the young to become mobile and strong enough to be seen above the edge of the nest. Potentially, the first sighting of this year's young, in the Montlake nest, will probably be in the second half of April. 

In the meantime, you will be far less likely to see pairs of adult eagles in their favorite hunting spots. In Monty and Marsha's case that would be the Cottonwood tree in front of Husky Stadium. 

For the next month or so, I would expect one adult, from each of the local pairs, to be in the nest incubating the eggs or protecting the young after they hatch. Initially, the other adult will often be sitting nearby watching the nest. They will be waiting and ready to fly over and protect the nesttheir mate, and their developing offspring from danger or harassment. 

However, after the young hatch, the demand for food will constantly increase. Ultimately, in two to three months the young will be larger and most likely eating more than the parents. Coming soon, there will be plenty of eagle action, i.e. hunting, to observe around Union Bay.

Have a great day on Union Bay...where nature lives in the city and Black Birders are welcome!

Sincerely,
Larry


Going Native:

Each of us, who breathes the air, drinks water, and eats food should be helping to protect our environment. Local efforts are most effective and sustainable. Native plants and trees encourage the largest diversity of lifeforms because of their long intertwined history with our local environment and the local native creatures. Even the microbes in the soil are native to each local landscape. 

I hope we can inspire ourselves, our neighbors, and local businesses to respect native flora and support native wildlife at every opportunity. I have learned that our most logical approach to native trees and plants (in order of priority) should be to:

1) Learn and leave established native flora undisturbed.
2) Remove invasive species and then wait to see if native plants begin to grow without assistance. (When native plants start on their own, then these plants or trees are likely the most appropriate flora for the habitat.)
3) Scatter seeds from nearby native plants in a similar habitat.
4) If you feel you must add a new plant then select a native plant while considering how the plant fits with the specific habitat and understanding the plant's logical place in the normal succession of native plants. 

*************** 

Keystone native plants are an important new idea. Douglas Tallamy, in the book "Nature's Best Hope ", explains that caterpillars supply more energy to birds, particularly young birds in their nests, than any other plant eater. He also mentions that 14% of our native plants, i.e. Keystone Plants, provide food for 90% of our caterpillars. This unique subset of native plants and trees enables critical moths, butterflies, and caterpillars that in turn provide food for the great majority of birds, especially during the breeding season. 

Note: Flowering plants and trees, i.e. those pollinated by bees, are also included as Keystone Plants.

Seeing Snipe

When most people think of snipe hunting they imagine an innocent person being told to wander around in the dark while hoping to catch some illusive, nonexistent creature. Snipes can be challenging to see, but they are real.

Earlier this month, near the small, repaired bridge over Arboretum Creek, I saw this one. If it had not been facing me, i.e. providing a bit of contrast between its belly and its surroundings, I might have missed it.

(This is the same bridge that was hit by an airborne car a year or two ago. For months, the bridge had bright orange barricades instead of the normal metal railings. It is just southeast of the intersection of Lake Washington Blvd and Boyer Street in the Washington Park Arboretum.)

This part of Arboretum Creek was enhanced with native plants in 2017 as part of the Loop Trail Project. This area of the creek is currently maintained by Seattle Parks and Recreation with assistance from the Friends of Arboretum Creek, The University of Washington Botanic Gardens, and The Arboretum Foundation

Last year, a young woman doing her UW Capstone project reported seeing a Snipe further downstream along Arboretum Creek. I have seen them many times in Duck Bay, further down beyond the mouth of the creek, however, this was my first time spotting one along the creek. 

This sighting tells me that the creek is no longer just a ditch for Lake Washington Blvd runoff. The return of the Snipe is nature's way of saying "Good job! Well done." They stopped to feed here because a healthy ecosystem is coming back along the creek.

Here is an example of a typically camouflaged view of a Snipe. (It is slightly to the left of the center.) If you look closely you will notice the bird is looking back at the camera.

While taking the photos I would occasionally stop to make sure the photos were turning out OK. Each time I looked away from the Snipe I would have to search hard to find it again. Even though my feet, the Snipe's feet, and our relative positions remained virtually unchanged

I am sure the snipe noticed me, however, it seemed confident that I could not see it. I love it when wild creatures just go on about their business as if I wasn't there. The Snipe was feeding on worms.

It would grab them with the tip of its bill, sometimes reaching deep into the mud, and then slurp them up. Actually, I suspect its tongue was pulling the worms up into its mouth.

Unlike a Great Blue Heron or a Belted Kingfisher Wilson's Snipes do not throw their heads back, and use gravity to help pull their prey into their mouth. If anything the Snipe consumed its food more like a Pileated Woodpecker or a Northern Flicker eating ants. 

There were no extravagant movements just constant and efficient feeding. The eyes of a Snipe are placed on the sides of its head. They can see in a three hundred and sixty degree circle, even when their bill is embedded in the ground.

Later in the morning, I stopped by again. The Snipe had only moved a few feet when a flicker of motion caught my eye. (Did you notice that its bill and legs are about the same length?)

A pair of Mallards floated into view while feeding in the creek. Spring is coming and if anything the female seemed a bit more focused on feeding than the male. I suspect part of the male's evolutionary job is to be on the lookout while the female build up nutrients so she can lay a dozen or more eggs come Spring.

The Snipe was probably five or six feet from the open water where the Mallards would pass by. Mallards can weigh as much as two and a half pounds while Snipes usually weigh under six ounces. Immediately, I began wondering if the Snipe would fly. (I wasn't expecting that the Mallards would attack the Snipe, but the size difference is so great that even accidental contact could damage the Snipe.)

The Snipe stopped feeding and carefully watched the Mallards' progress.

It began stretching a wing, just in case it needed to fly.

I was amazed at the bright orange of the tail feathers, partially visible behind the primary wing feathers.

After it closed the wing the spread of the tail feathers remained wider than normal, indicating it was fanning and stretching its tail as well.

A moment later it raised both wings above its back without unfolding them. Stretching out a different set of muscles.

It seemed like scratching its neck might be its final flight preparation.

Notice how the tail feathers are now back to the "normal" resting width with most of the feathers stacked one on top of another.

The Snipe peered back at the Mallards as if trying to decide if they were really a danger or whether it was safe to continue feeding.

The Mallards continued feeding. They did not seem to notice the Snipe.

The careful Snipe also returned to feeding. However, it kept turning so it could keep a watchful eye focused on the Mallards.

Suddenly, there was a great thrashing and splashing of water by the male Mallard. Immediately, the Snipe stood tall and watched with keen interest.

The Mallard caught a dark-colored creature. He immediately turned his back on the female Mallard and started moving upstream. He kept his body between his treasure and his mate. The female sensing something special was afoot crept closer, as if waiting to gobble up anything the male happened to drop.

Mallards, unlike Raptors, are not equipped with sharp bills that can quickly dispatch living prey. Much of the year they eat mostly vegetation, during breeding season they eat more larvae, worms, and other small creatures that they can easily swallow. 

The creature the Mallard caught was probably five or six inches long. It would be a feast for the Duck, if it could manage to subdue it, and also not lose it to the female. In the past, I have seen bull frogs in the Creek. I wondered if the Mallard had caught a very large tadpole.

I occasionally saw the tail of the creature as it struggled.

 The Mallard could only squeeze it, repeatedly, until the resistance ceased.

During this whole process, the Snipe stopped feeding and stood stiffly at attention - like a soldier at the funeral of a fallen friend.

The female stayed very close as the male worked its way slowly upstream.

For a moment, it appeared the Mallard lost its catch.

Howeverit was just the final rinse before consuming the Northwestern Salamander.

This was also my first time seeing a Salamander in Arboretum Creek. In 2021, I did see one being removed from the Lower Woodland Garden pond, which is downstream and up a seasonal rivulet to the east. Click Here to read the story and see the photo of the Barred Owl that caught that Salamander. 

Click Here to find the Lower Woodland Pond on my map, which also includes nearby nest sites.

As the Mallards disappeared around the bend...

...the Snipe continued to pay close attention.

Then, it turned and looked directly at me, almost as if to say, "Did you catch all that?"

Finally, with the danger passed, the Snipe returned to feeding.

On this occasion, the worms the Snipe was eating were relatively large and visible. I understand with smaller items they can pull them up and swallow them even while their bill is stuck in the mud and searching around for more food.

The next day and the day after there were two Wilson's Snipe at this location.

Have a great day on Union Bay...where nature lives in the city and Black Birders are welcome!

Sincerely,
Larry

There are two different plants in this May, 2019, photo. One is native to our area and one is not. Do you know which is which?









Scroll down for the answer.







******************







Tall Oregon Grape: The native plant on the left. It belongs in our yards and is a contributing member of a healthy PNW ecosystem.

English Holly: The non-native invasive plant on the right. If left unchecked it will cover up and shade out native plants. The Holly reduces the richness and health of the ecosystem, and it is poisonous to humans and pets.

These two can be confused, especially, in the Winter, when they are without fruit or flowers. 

Learning to distinguish these plants will help us to protect the local ecosystem. A key difference, which I am still working to remember, is that on the native plant the leaflets are in pairs, directly opposite of each other, except for the final leaflet. It is like they are working together, maybe that can help us to remember this species works together with other native plants and creatures in the PNW. 

With English Holly, the leaves sprout out at alternating locations. It is as if each leaf is only concerned about itself and its own growth.
