A northwest and north view across Pool F to the highlands in the

may be able to see the adult and immature Bald Eagles perched in the

A northwest view across the south lake to the bluff area on an overcast day. Compared to earlier in the day (and later) only a "few" waterfowl were present. Approximately 65 to 70% of the lake was ice-free. 12/10/14 (Wolf. Oesterreich)

Dec 12, 2014: Trumpeter Swans
Trumpeter Swans have been common the south lake, especially early
in the morning and in the afternoon and evening. Tonight (12/9) I
counted 38 (25 adults & 13 juveniles). These swans were heading out
to feed. 12/9/14 (Wolf. Oesterreich)

Canada Geese lay on the ice while Mallards swim in the icy water on the south lake looking west. Hundreds of birds were on the lake this morning. 12/9/14 (Kevin Kane)

A few Common Goldeneyes have been found on the south lake. The

Dec 1, 2014: Wolf's November 2014 Wildlife Report
This Northern Shrike (first winter form) was found along the Upland Trail on the 23rd. [A digiscoped photograph.] 11/23/14 (Wolf. Oesterreich)
A total of 77 avian species (plus 1 sp.) was recorded this month, ranking this month as the highest November (tied with November 2010) among 17 years of records. The Gray Partridge on the 12th was #268 for my Park List.
Based on citations in the 3rd Edition of “The Birds of Story County, Iowa,” by
Stephen J. Dinsmore and Hank Zaletel (2001), plus my personal updates to the
records, the White-winged Scoters on the 12th may represent only the
6th record for Story County. The
Western Grebe on the 14th may be the 8th record for the
County. The Hermit Thrush on the 23rd
may represent a new extreme late Fall record (former record set on 31 October
1984 at Brookside Park).
Listed below, following the species’ names, are the date(s) of
sighting(s), plus the occasional miscellaneous information regarding numbers,
gender (♂=male, ♀=female), age (im=immature, ju=juvenile, abp=adult breeding
plumage, ad=adult, anb=adult non-breeding), color phase (b=blue, w=white), and
location (BY=back yard). ). The order follows the 54th Supplement (2013) to the American Ornithologists’ Union Check-list of North American Birds and the 13th
Supplement to the 7th Edition (1998).

Geese on the south lake (looking north). 11/23/14 (LaDan Omidvar)
Sunday, November 23, 2014, 2:00-3:30 pm, Cloudy, no wind, Temperature 51 degrees F.
I set up my spotting scope on the south lake this afternoon to watch the waterfowl. I estimated there were about 3100 Canada Geese on the lake. Among them were a few Cackling Geese, Mallards, Common Mergansers, Redheads, Goldeneyes, Coots, and Pied-bill Grebes. The goose flock was smaller than yesterday when I estimated more than 4000 plus Trumpeter Swans. No swans today.
About 3:30 the sky got darker and a rain shower moved through behind a strong west wind. Although I was wearing a rain coat, I got very wet from the waist down by the time I reached the car. Now is a good time to view waterfowl at the park. I hope you can find time to take advantage of the opportunity.
A few days ago, I had the opportunity to view an immature Northern Goshawk in my back yard. Goshawks are infrequent visitors to Iowa in the winter. I don’t see a big variety of birds in my backyard because of where I live in the central part of Ames. Mostly House Sparrows visit my feeders along with a few Northern Cardinals, Black-capped Chickadees, Downy Woodpeckers and Bluejays. If I’m lucky, once or twice a year, I might see a resident Coopers Hawk or a migrant Sharp-shinned Hawk swoop in and catch a House Sparrow. Both of these birds of prey, as is the Northern Goshawk, are in the family Accipitridae and the genus Accipiter. Accipiters prey primarily on other birds. I first caught a glimpse of the hawk perched on a large brush pile and I saw that it had the characteristic long tail of an accipiter. I quickly ran to get my binoculars and moved to the sun room for a better view. The hawk then made a pass at a fox squirrel that was scavenging sunflower seeds on the ground below the bird feeder. This provided a good close-up view and I could see that it was much larger than a Coopers Hawk. It would be highly unusual for a Coopers Hawk to go after a squirrel. I thought, immature Red-tailed Hawk? No, the spotting on the breast and the markings on the tail were not right. I got good views of the bird from several angles as it tried several more times to catch a squirrel. Every time, the squirrel was too fast and dove into the brush pile. I was able to make out a faint white line over the eye, characteristic of the adult of this species. I consulted three different field guides that I had on hand and decided that it was definitely an immature Northern Goshawk. After about five minutes, the young bird gave up and flew off toward the north.

Monarch butterfly. 9/13/14 (Wolf. Oesterreich)
Thursday, November 20, 2014, Sunny, 100 percent snow cover, Temperature 26 degrees F.
Aging and weather have reduced my ability to walk at the park as much as I would like, so I have been catching up on my reading. "Cultivating an Ecological Conscience—Essays from a Farmer Philospher" by Frederick L. Kirschenmann is a book I have been putting off reading far too long. Early in the book, Fred says that farming with love and respect for the land and its healthis similar to the quandary that a naturalist such as Barry Lopez experiences. He writes, “Immersed in nature, the naturalist experiences the loss and pain of the damage we have done to nature. But science demands that one remain detached. How, then, does one ‘manage emotional grief and mixed indignation in pursuits so closely tied to science, with its historical claim to objectivity’? Lopez observes that ‘the modern naturalist, acutely, even depressingly, aware of the planet’s shrinking and eviscerated habitats, often feels compelled to do more than merely register the damage. The impulse to protest, however, is often stifled by feelings of defensiveness, a fear of being misread…Almost every naturalist has borne the supercilious judgments of various sophisticates who thought the naturalist a romantic, a sentimentalist, a bucolic—or worse; and more latterly, the condescension of some scientists who thought the naturalist not rigorous, not analytical and detached enough.”
During my career as a scientist and a naturalist, I was often troubled by the tension between the need to be objective and the emotional desire to defend the natural world. The scientist side of me wanted to know and understand nature but the naturalist side saw the beauty and mystery. What a pleasure it was to hear Richard Dawkins speak in Ames last Monday night and defend the art of observation, reason and deduction as a legitimate scientific endeavor. My graduate research was guided by this approach which, at the time, was very acceptable.
With a doctoral degree in hand I was hired to determine how pesticides in the environment were affecting reproduction in birds. To do so, required quantitative data and laboratory experiments followed by objective analyses that could be published in peer-reviewed journals and even stand up in a court of law.
Now, that I am retired, I find that it is more enjoyable to be a naturalist again and to be content with just observing and describing the beauty of nature. But how can one not object to the loss of the passenger pigeon or the potential loss of the monarch butterfly and the polar bear?

Nov 17, 2014: Trumpeter Swans
Two adult Trumpeter Swans and their 4 cygnets were present on the
north lake during the snowfall. That is, until an unethical kayaker
from Boone County scared them off. (He has a history of harassing
migratory waterfowl!) The swans settled down on the south lake, but
were gone on Sunday. Instead, another couple, with only 2 cygnets, had
shown up. 11/15/14 (Wolf. Oesterreich)

Nov 8, 2014: Hope to Hang Onto
From Todd Burras' Ames Tribune Column, 10/11/14
http://amestrib.com/blog/woods-wildlife-and-wanderings/hope-hang.html
The tiny white fragments of shell weren’t exactly what I was hoping for, but as evidence goes, they’d at least provide some.
This was my second trip to Ada Hayden Heritage Park in the past couple weeks to check the two mallard hen houses (photo above) I placed on a pair of wetland cells on the west side of the park several years ago. I was unprepared the first time, wearing knee-length boots rather than chest waders. Today, I was prepared.
