A Backyard Bird

A male House Finch is a beautiful bird. Originally, they were from the southwest, which is implied in the second half of their scientific name, Haemorhous mexicanus. Today, House Finches can now be found in 49 out of the 50 states. Many years ago, they had some human help in getting to both New York and Hawaii. During the following decades, they made good use of the opportunity to dramatically expand their range. It's not surprising that a bird that originated in the desert has yet to establish itself in Alaska.

In general, House Finches tend to migrate vertically. When the snow reaches the mountains they like to come down into snow-free cities and make good use of the warmth and the seeds which they find in our bird feeders.

This female finch appears to be collecting the leaf stem from a Big Leaf Maple to be used in nest building.

For the most part, females lack the bright coloring of the adult males. Immature birds, of both genders, also wear basic brown.

Males get their red coloring from the fruit they eat. Depending on the fruit, their bright spots can occasionally be orange or yellow.

This August photo shows what appears to be a young male bird, which is apparently molting into its mature coloring. One clue to its youth is the fine streaking on the belly. Looking back at the two adult photos, you can see that their vertical belly stripes are not nearly as delicate.

In this June photo, if you look close, you can see that a male is regurgitating food for a full-sized young bird. After the young leave their nests the male birds apparently take over all of the feedings. This frees up the females to focus on producing their next brood. All About Birds says House Finches can have as many as six broods per year.

This October photo also shows a male beginning to get its color. 

In the fall, House Finches regularly dismantle the 'hops'  found on the Hophornbeam in the Arboretum (on the east side of Duck Bay) to consume the seeds. 

The gray-brown patch on the upper cheek is one way the colorful males can be distinguished from Purple Finches. You can learn more about their differentiating features by Clicking Here.

Since almost all of us are spending an abnormally large amount of time at home, this might be a good time to watch for nest-building behavior in your backyard. The House Finch starts with relatively larger twigs to build the supporting structure of the nest.

They progress to smaller and softer materials.

In this case, the female is eyeing the opening in the bushy conifer that leads to her nest site.

There is no way to view this nest, which is wonderful. Her eggs and her young will be much more likely to survive in such a nicely hidden location.

Later, she brought in what appeared to be thin strips of shredded bark.

Although, from this angle, it looked more like dried grass.

Her mate occasionally helped.

Bringing in this very fine white material seemed like an indication the nest was nearing completion. 

I really have no idea what type of plant could produce such a long thin fragment, but it sure looked soft and warm, just like a baby's blanket.

The materials the finches are using could be considered hints to making our backyards into wildlife sanctuaries. Leaving grass to grow tall and dry out, leaving the down from flower and tree blossoms, leaving bark that is decaying and falling off trees and leaving last year's leaves to decay on top of your flower beds could provide almost all of the materials seen in this post. Also, having some thick conifer shrubs or trees, hopefully, with vegetation all the way to the ground, could provide some nice hidden nesting spots.

Generally, the male accompanies the female where ever she goes. Sometimes he helps bring nesting material, and sometimes he appears to be simply standing guard. In this photo, he was waiting patiently while she updated the nest. When he tilted his head, it seemed obvious that he was listening to a nearby House Finch singing its warbling song. 

When the neighbor took a breath, the male visibly raised his head, despite the rain.

He opened his mouth and replied with his own version of the House Finch melody. As the two birds took turns singing, the male looked around apparently trying to find the source of the sound. 

Clicking Here will take you to an example of a House Finch song on All About Birds. Often at the end of a phrase, a House Finch will produce a somewhat less melodic sound. In my mind it makes me think, 'Splat'. Since no other finch makes that final sound, I find it very useful in identifying the song of a House Finch, even when I cannot see them.

Have a great day on Union Bay or...in your own backyard!

Going Native:

Without a well-funded Environmental Protection Agency, it falls to each of us to be ever more vigilant in protecting our local environments. Native plants and trees encourage the largest diversity of lifeforms because of their long intertwined history with our local environment and native creatures. I have been told that 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 to 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. (If natives 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.

My intention in my weekly post is to include at least one photo each week and visually challenge us to know the difference between native and non-native lifeforms.

The Email Challenge:

Over the years I have had many readers tell me that Google is no longer sending them email announcements regarding my posts. Even more frustrating when they go to 're-sign-up', hoping that will enable them to once again start receiving the announcements, they get a message which says 'Sorry, you are already signed up.' Google has not responded to my requests for help with this issue. 

My functional workaround is to set up my own email list and each week I manually send out a new post announcement. If you are experiencing the issue and would like to be added to my personal email list please send me an email requesting to be added. Thank you for your patience!

As a reward to those who have read this far, here are a few more House Finch photos.

Finches generally have a 'notched tail', however, this example is a bit over the top. 

When birders refer to finches having 'notched tails' this is what usually comes to mind. The previous photo does demonstrate why the subtle, 'perched' notch exists.

Fits The Bill

Last year my friends Anne and Rick Matsen invited me to come and take photos of blossom-twirling birds, which return to their backyard on an annual basis. A few weeks ago the timing finally came together. The hungry House Finch, the Cherry Blossoms and the evening sunlight all appeared at the same time.

The experience was a first for me. I had never seen anything like it. The finches plucked the blossoms off the tree and manipulated them with their beaks. 

I would not have been surprised to find the birds eating cherries off the tree later in the year, but consuming the green partially-developed buds, while hiding behind the blossoms seemed odd. 

Apparently, when the blossoms burst into full bloom, the buds reach a particularly tasty state. I am thinking there may be sugar in the buds, created in the process of producing nectar to attract pollinators.

I doubt that the finches are actually helping with the pollination, however professional cherry growers usually 'thin' their cherries to increase the size of the surviving fruit. Possibly, the House Finch intervention actually increases the volume of fruit which the tree produces. 

As the finch work to secure their feast, the petals flutter slowly to the ground. I suspect Anne and Rick simply enjoy the spectacle without regard for the production of fruit.

The process reminds me of snowfall, without the need for long underwear.

The beauty of nature in action seems like a fitting Mother's Day gift. This post is dedicated to both my mother and my wife. Without their consistent love and care neither I, nor my children would be here today.

While reviewing these photos, I was impressed by the thick heavy bills of the House Finch. Clearly, their bills enable them to crush seeds, pods and buds in order to extract sustenance. This inspired me to consider the variety of ways in which relatively small birds' bills and tongues are uniquely adapted to help them find food.

Golden-crowned Kinglets have tiny, elegant little bills. Their bills are so light-weight that they help enable the kinglets to swiftly grab insects in flight.

Hummingbirds have long, thin, bills and tongues which enable them to reach deeply inside a blossom to secure the nectar. 

Downy Woodpeckers have short, sharp beaks with a stout base for drilling holes in woody plants and decomposing trees. 

They also have relatively long, barbed tongues, with which they reach in and pull out juicy little lifeforms like larva.

Cedar Waxwings have fairly small bills, but very wide mouths. No doubt this arrangement helps with swallowing fruit whole. In addition, their tongues have a rear-facing projection which resembles a fish hook. Actually, it may be that fish hooks resemble their tongues. Once their food passes beyond the hook, the hook can then sink into the soft fruit and pull it down into their throat.

Varied Thrush have a similar tongue, although the rear-facing hook may be slightly less defined.

Pied-billed Grebes have surprisingly thicks bills, which help them crush and hold small slippery fish. Birds of North America says, their bills also enable them to consume crayfish, despite the hard exoskeleton. See the reference below. 

The reference refers to research done by my friend and mentor, Martin J. Muller. Martin has also been working on a wonderful new website called, UrbanRaptorConservancy.Org.

Red Crossbills have one of the most sophisticated and interesting adaptions of all. Their bills enable them to reach between the scales of a pine cone and pry it open. This allows access for their tongues to reach the sharply-defended pine nuts, which are quite safe from most other avian species.

White-crowned Sparrows have bills which look like miniature versions of the House Finch bill. This enables them to eat mostly small seeds, but they occasionally supplement their diet with insects and such.

The relatively short sharp bill of the red-breasted nuthatch is like the Swiss Army Knife of bird bills. 

Not only do they gather and cache seeds, they also catch insects and other lifeforms as well. This photo, taken earlier in the week, fits nicely in a Mother's Day weekend post. It shows a mother returning to the nest with a nice white spider for her young.

By the way, you might want to compare the eye stripes and caps of the nuthatches in these last two photos. The crisply black head markings indicate a male, while the lighter gray-black coloring indicates the nuthatch is female. 

Brown Creepers use their slightly decurved bills to reach in and around crevices in the bark. Given that they are almost always seen searching for small living creatures on tree trunks and branches, I suspect they would not do well as vegetarians. 

A Merlin has the the flesh-rending bill of a predator. While this is a beautiful an elegant little bird, it is clearly a carnivore.

It is amazing how nature has produced so many variations in bird bills. The thousands of possibilities worldwide go far beyond these few local examples. However, in all cases, the variations in bills fit the variation in food sources. 

Regardless of the species, they all have one thing in common, none of them, or us, would be here without our mothers. Happy Mother's Day to one and all!

Have a great day on Union Bay...where Mother Nature survives in the city!

What species of tree is this? Is it native to Union Bay?

Horsechestnut: This tree is native to the southeastern portion of Europe. It thrives in our Pacific northwest habitat, however I would prefer one of our native Bigleaf Maples (BLM). The BLM has a similar size and shape and is adapted to coexist with our native flora and fauna.
