The Measure of Success, A Sunday Special Edition

Sunday, February 3, 2013

The Measure of Success
"That land is a community is the basic concept of ecology, but that land is to be loved and respected is an extension of ethics. …  We abuse land because we see it as a commodity belonging to us. When we see land as a community to which we belong, we may begin to use it with love and respect. …  Examine each question in terms of what is ethically and aesthetically right, as well as what is economically expedient. A thing is right when it tends to preserve the integrity, stability, and beauty of the biotic community. It is wrong when it tends otherwise."  -  Aldo Leopold

This past week I have had the pleasure of being involved in several programs dealing with various aspects of the San Antonio River Mission Reach and the River Restoration Project. To end the week, yesterday morning (Saturday, February 2, 2013) I participated in a birding hike sponsored by the San Antonio River Authority.

The photos in this series are from that hike. During the morning, we covered the area roughly bounded by Lone Star Blvd to the north, the western half of Roosevelt Park then south along Mission Rd to the railroad tracks just north of U.S. 90 and the San Antonio River Greenway to the west.

The goals of the San Antonio River Restoration Project are philosophically and ethically consistent with the Aldo Leopold quote with which I opened this post. One of the primary goals of the project is to provide habitat for birds that migrate along the Central North American flyway.

One measure of the success of the project is the number of birds that can already be found along the Mission Reach, even though the project is far from completion. In a sense, these birds are the "canaries in the coal mine" that indicate the habitat improvement is working.

Yesterday a total of twenty seven species of birds plus one sparrow of unidentified species (not a house sparrow were sighted. The photos presented here include thirteen of those twenty seven species:

  • The first photo is a spotted sandpiper. This particular sandpiper has its spotless winter plumage.
  • Photos two and three are a 'Myrtle' yellow-rumped warbler.
  • Photo four is an European starling. These birds were first introduced to New York City in 1890 and have since spread throughout the entire continental United States.
  • Photo five is a house finch.
  • Photo six is a house sparrow landing at the top of a twig. Growing up in St. Louis, we referred to these as English sparrows which indicates their Eurasian origin. Like the starling, they were introduced from Europe. They have spread worldwide.
  • Photo seven is a red-tailed hawk. This hawk was in the process of building its nest and can be seen carrying a twig in its beak in this photo.
  • Photo eight and nine are a little blue heron. There were a pair of them on the river yesterday. This pair has returned to Bexar County a little early this year. They usually don't return until mid-March.
  • Photo ten is a great egret. They are year around residents. The river wouldn't be the same without them.
  • Photo eleven is a loggerhead shrike perched at the top of a tree seventy to seventy five yards away from the camera. I wouldn't have been able to identify this shrike based solely on this photo, but fortunately, we did get a better look at it while we were there.
  • Photo twelve is a pair of gadwalls. There were at least five or six pair on this section of the river yesterday.
  • Photo thirteen is a great blue heron. Great blue herons are close cousins of great egrets. Both are in the Genus Ardea.
  • Photo fourteen is a neotropic cormorant.
  • Photo fifteen is another red-tailed hawk. There was a pair of these hawks nesting on top of a cell phone tower.
  • Photos sixteen and seventeen are feral monk parakeets. These parakeets are native to central South America. They were first introduced to the United States in 1967. Feral colonies are becoming increasingly common throughout the East Coast and Gulf Coast states. There is a flock of them nesting in an electric transmission station on Mission Rd.
Note: This post has been updated, 5 February 2013 at 3:15 PM, from the original to correct the number of species sighted on this bird hike.

Flying Beyond the Beautiful, A Sunday Special Edition

Flying Beyond the Beautiful
"Our ability to perceive quality in nature begins, as in art, with the pretty. It expands through successive stages of the beautiful to values as yet uncaptured by language."  -  Aldo Leopold, A Sand County Almanac














This set of photos of a great egret was taken on my walk along the San Antonio River on Wednesday, December 19.

A footnote: I would love to get feedback from someone who is both an experienced birder and an experienced pilot on this series. What isn't obvious is the egret was flying into a wind gusting up to 25 mph out of the south as it landed. When the egret approached the weir dam, it had to adjust for the wind gusts and lower its air speed to land. I have no doubt it is completely routine for an egret, but it was awesome to watch. The total elapsed time from the first photo to the one where it's standing on the weir was 2 min 42 sec.

Things Natural, Wild and Free; A Sunday Special Edition

Things Natural, Wild and Free
"Like winds and sunsets, wild things were taken for granted until progress began to do away with them. Now we face the question whether a still higher 'standard of living' is worth its cost in things natural, wild and free. For us of the minority, the opportunity to see geese is more important than television."  -  Aldo Leopold
The first challenge of birding is to spot a bird:

This set of photographs was taken at the Mitchell Lake Audubon Center yesterday morning during an Alamo Area Master Naturalist training field trip. A special note of thanks goes to Tom and Patsy Inglet for their expert and enthusiastic guidance.

There are still quite a few birds I am learning to identify. Some I am more certain of than others. Going down the series from top to bottom:
  • The first two photos appear to be of a Northern Harrier.
  • Photos three through nine are of a juvenile Red-tailed Hawk with a swallow chasing it in the eighth photo.
  • Photo ten I have yet to identify with any certainty.*
  • Photo eleven is an Eastern Phoebe.
  • Photo twelve appears to be either a Northern Harrier or an American Kestrel.
  • Photos thirteen and fourteen are of a Crested Caracara.
  • Fifteen and sixteen are of a very spectacular Vermillion Flycatcher.
  • Seventeen is a Scissor-tailed Flycatcher.
  • Eighteen is a Wilson's Snipe.
  • Nineteen through twenty-two are American White Pelicans.
  • Twenty-three is a flock of Double-crested Cormorants.
  • Twenty-four appears to me to be a Lesser Yellowlegs.
  • Twenty-five is a  Black-necked Stilt.
  • Twenty-six includes Mallards, a Black-necked Stilt and American Avocets.
If anyone can provide an identification I have missed or a correction, please feel free to send me an email at dhewers@gmail.com.

* Update, January 10, 2013: Photo ten is a Least Sandpiper. When I first posted this I hadn't had time to verify the identity of the bird. Least sandpipers were present in great abundance, literally in the hundreds, the day these photos were taken.
