Friday, March 29, 2013. Sunny, warm, southerly breeze, Temp. 55 degrees F. Beautiful day.

After a cold month with several days of snow the warm weather has brought out lots of park users. Snow melt has filled most of the wetland ponds and the main lake is nearly full as well. I parked on Harrison Avenue and walked around the south lake. A plethora of waterfowl were evident and I am sorry I didn’t bring my spotting scope. On the wetlands near the parking lot I saw four Blue-winged Teal, a pair of Canada Geese and two Gadwall. About 20 Shovellers were dabbling in Pond F of the north wetland. Ring-billed Gulls and American Crows were flying around everywhere and a flock of about 75 gulls were sleeping on the ice in the western half of the south lake; the eastern half is open water. A pair of unmarked Trumpeter Swans were on the edge of the ice in the center of the lake and several dozen Canada Geese were on the ice near the south shore. I scanned a large flock of ducks in the open water just beyond the ice and identified the following: Canvasback, Redhead, Ringed-Neck Duck, Common Merganser, Red-breasted Merganser, American Widgeon, Gadwall, Lesser Scaup, Bufflehead, Mallard, Ruddy Duck, and an American Coot. I probably could have seen more species had I brought my spotting scope. An immature Bald Eagle was standing on the ice near the flock of gulls; it later flew southeast towards the Skunk River. A flock of about 15 Canvasbacks flew in from the southwest, dipped low over the flock of ducks in the water and then made several passes over the lake before regaining altitude and flying northward. The ponds near Stonebrooke are still mostly frozen but a large flock of Ring-billed Gulls and a couple of Herring Gulls were on the ice there. Kevin Kane's blog had spectacular photos this week from Wolf Oesterreich of a pair of White-fronted Geese and a Ring-billed Gull in flight.

March 28, 2013: Ring-billed Gulls



On the south lake ice and hunting over Pond M were over 40 Ring-billed Gulls.  (Amongst them were 2 adult Herring Gulls, the first ones seen this year.) 3/28/13 (Wolf. Oesterreich)

March 26, 2013: Greater White-fronted Geese


Greater White-fronted Geese over the south lake. 3/23/13 (Wolf. Oesterreich)

Thousands of Greater White-fronted Geese have been migrating northward. Hundreds have been stopping at the Park, mostly on the south lake and Pool F. Their vernacular name "speckle-bellies" comes from the black markings on the belly. Their laugh-like call distinguishes them from the honking Canada Geese.

March 25, 2013: Immature Bald Eagle


 
Immature Bald Eagle. 3/23/13 (Wolf. Oesterreich)
 
Immature Bald Eagles have been a constant presence for most of the month. Lately, a group of 3 have been hanging out out together. I've seen them perched in the trees at or near the bluff area. A 4-year bird (not quite complete white head and tail) and 1 to 2 adults have also been observed. Sometimes you may have the privilege of watching an eagle dive-bomb at a group of waterfowl on the south lake, either for "fun" or to locate a potential meal. On the 20th, I saw two large birds fly from the Skunk River area over to the south lake. I soon realized that it was an adult Bald Eagle chasing a Greater White-fronted Goose. The eagle matched exactly the goose's turns as they circled over the water. After a minute the eagle broke off and flew back towards the river.

Blue-winged Teal, 3/23/13 (Wolf. Oesterreich)

The first and only pair (so far) of Blue-winged Teal has been seen at Pool J (middle wetland complex) since the 19th.  They are hanging out with Canada Geese and Lesser Scaups.  A single male Green-winged Teal has also been present for the past 2 days.

Great Blue Heron, 3/22/13 (Wolf. Oesterreich)

A Great Blue Heron has been observed at the Park since the 19th, usually near the weir between Ponds M and N (south wetland complex).  With cold nighttime temperatures causing ice to form over open waters makes it hard for the bird to find places to feed.  This photograph shows the heron taking flight from the mudflat at the SW corner of the south lake.

March 17, 2013: Erv's Field Notes #54


Canada Geese in flight over north lake on a sunny February day at near sundown. 2/23/13 (Kevin Kane)

In previous field notes and on Kevin’s blogs, Wolf and I have mentioned several different names for geese observed at Ada Hayden Heritage Park. These include Canada Goose, Cackling Goose, White-fronted Goose, Ross Goose and Snow Goose (blue and white phase).

Here I will just talk about the various forms of Canada Geese. Let’s start with the definition of a species. Taxonomists (people who name species) first used morphological characters to describe and name a species. One of the most famous taxonomists was the Swedish naturalist, Carl Linneaus (1707-1778), who spent his entire life describing and naming preserved plants and animals brought to him by explorers of the new world. Linneaus devised a binomial system of nomenclature, that is, each species was given two Latin names, the genus and species. This system is still in use today. Closely related species were given the same genus name. Later, a trinomial system came into use for closely related species, to designate what zoologists called the subspecies and botanists called a variety.

In the mid-20th Century, biologists agreed that morphological characters were no longer sufficient to fully describe a species. For example, sometimes males and females of the same species were so different morphologically that they were named as separate species. The great ornithologist, Ernst Myer, devised a biological definition of a species that has been widely adopted. This definition states that a species is a population of individuals that interbreed, or that can potentially interbreed with each other, but cannot interbreed with other populations. Many populations show geographical variation in their morphology and biologists use the subspecies designation to identify them. Not surprisingly, biologists often disagree in these designations leading to confusion in the naming systems. This is very evident in the world of Canada Geese. This species has a great amount of geographical variation across its range in North America and many subspecies have been named to designate the many subpopulations. One long-time student of Canada Geese claimed that he could recognize 135 subspecies. However, in 1991, at an International Symposium on the Canada Goose held in Milwaukee, Wisconsin, Gerald Shields, presented a thorough analysis of the phylogeny of North American Canada Geese based on mitochondrial DNR. He showed that Canada Geese can be divided into two major groups which last shared a common ancestor about one million years ago. One group, which is primarily continental in its breeding distribution, is composed of all large bodied subspecies consisting of seven subspecies. The second group, which breeds in coastal Alaska and Arctic Canada includes four small-bodied subspecies. More recently, it has been shown that several subpopulations of the smaller Canada geese can be considered as a full species. Thus, under the rules of nomenclature, the name for the Cackling Goose had precedence, so the Richardson’s Canada Goose now is called the Cackling Goose, Branta hutchensii.

This is a long-winded preamble to explaining what we observe at Hayden Park. The most numerous of the geese wintering in Ames is the Giant Canada, Branta canadensis maxima. The Giant Canada is a non-migratory subspecies breeding mostly in Midwestern states although it has been introduced into southern states as far south as Florida. A small number of a slightly smaller goose, Branta canadensis interior, is present. The Interior Canada is difficult to distinguish from the Giant Canada in the field. This subspecies breeds along the western shore of Hudson Bay in Canada and winters from Iowa south to Louisiana. A few dozen Cackling Geese have been using the park this winter. This species breeds in the arctic regions of northern Canada and most of this population winters in northern Missouri at Swan Lake National Wildlife Refuge. The Cackling Goose is not much bigger than a Mallard duck and has a very short bill. Otherwise it looks like all of the other geese in the flock. So, the next time you are out at the park, take along a good pair of binoculars or a spotting scope and see if you can pick out these three kinds of geese that all look like alike at first glance. I’ll say more about the other three species of geese in a later note.

March 7, 2013: Ding Darling video on Iowa Public TV this week


Wildlife on the edge of the city.  2/25/13 (Kevin Kane)

This week, Iowa Public TV is broadcasting the production “Americas Darling: the story of J. N. Ding Darling.”  Paul Skrade and Erv Klaas are interviewed in the production. 
Ding Darling was an cartoonist for the Des Moines Register in the early 1900’s and is well known for his political cartoons, many about conservation.  He was the commissioner of the Iowa Fish and Game and the head of the U.S. Biological Survey, which was the forerunner of the U.S. Fish and Wildlife Service.  He was influential in the establishment of the first Cooperative Research Unit—which was at Iowa State College!  He started the Duck Stamp program, and he was the first president of the National Wildlife Federation .  The show is very informative and entertaining.  The schedule for this week and in early April is:
Fri, March 8, 2013 5:00 PM (IPTV World)
Sat, March 9, 2013 8:44 PM (IPTV World)
Sun, March 10, 2013 2:00 PM (IPTV)
Mon, April 8, 2013 9:00 PM (IPTV)
Enjoy it, if you have a chance.  You can see the “trailer” here: http://www.iptv.org/video/detail.cfm/32597/jdd_20130211_americas_darling

March 2, 3013: Wolf's February Species Report


Mallards on the ice shelf of the lake. 3/2/13 (Wolf. Oesterreich)

A total of 53 avian species was recorded this month, ranking this month as the highest February among 16 years of records. February 2005 and 2011, with 40 species each, were the previous high total.

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 Ross’s Goose first observed on the 19th may be an extreme early Spring record for Story County (former record set on 9 March 1991 at Hendrickson Marsh). Other extreme early Spring records include the male Wood Duck on the 16th (former record set on 19 Feb 2005 at AHHP), the male Lesser Scaup on the 17th (former record set on 19 Feb 2002 at Hallett’s Quarry), the female Common Goldeneye on the 4th (former record set on 21 Feb 2011 at AHHP), the Hooded Merganser pair on the 18th (former record set on 20 Feb 2011 at AHHP), and the Pied-billed Grebe on the 18th (former record set on 5 Mar 2000 at Hallett’s Quarry). The continued presence of the Tundra Swan and the American Black Duck (through mid-month) are also noteworthy.

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 53rd Supplement (2012) to the American Ornithologists’ Union Check-list of North American Birds and the 12th Supplement to the 7th Edition (1998).
