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. 






A low-growing plant that is currently beginning to bloom around Union Bay,

Here is a better look at the foliage? Is it native to our area?

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!

My email address is: LDHubbell@Comcast.Net

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.

  1. Enjoyed you Blog today on House Finch. Your 2 photos of the House Finch with " ...very fine white material....soft & warm as a baby's blanket..." reminded me of one year when a neighbor's old light yellow Labrador dog would come visit almost every day. He loved to be brushed. One day I left the excess fur by the outside bench. I found the chickadees, etc. loved it for nest building.

    1. Thank makes a lot of sense. It also makes me wonder what type of fancy dog would have long white hair like that? :-)

  2. I'm curious as to where the pictures were taken. Barbed wire traps a lot of owls every year and they usually have to be euthanized due to wing damage. They hang there and struggle and twist on the barbs for hours or days until somebody sees them. Or they break free and wander off, unable to fly.

    1. This was along the boundary fence between the Arboretum and Broadmoor. I have not seen the situation you describe, hopefully, I never will.

  3. Well, I hate to do this then. I will send you a picture through email. I used to work with the Audubon wildlife Care Center so saw a few. The Care Center hates barbed wire. I'll send a picture of a Barred Owl caught on a single barb. It tore the flesh from the wing so it had to be euthanized. Maybe you can show it the arboretum people. There is no good reason for anyone without a cattle ranch to have barbed wire.

    1. i will ask, but I strongly suspect the fence belongs to the Broadmoor community. The Arboretum is a free city park which is open to anyone 99.9% of the time. It is the gated community that works to protect their exclusive property.
