Bunnimit, Manit
|
Common Raven
|
Lake Manawa State Park
|
[...] Lake Manawa State Park, near Council Bluffs, IA. [...] was travelling south on the road that follows the west edge of Lake Manawa.
|
|
The documentation letter by Manit Bunnimit is the only one submitted and forms the basis of this record. | Elimination of similar species: [...] It flew for most of the time by soaring with its wings held very flat, only twice flapping its wings momentarily (shallow wingbeats) and once folding its wings rather tightly and gliding. All of the crows I have seen flap steadily, gliding only occasionally. [...] It could not have been mistaken even for the tails of the occasional American Crows that appear quite rounded. The sheer size of the bird and the wedge-shaped tail were enough to distinguish it from any of the crows, but what about the Chihuahuan Raven? Fortunately, as it flew by, the bird made two brief call notes that were very hoarse (sounding much more like grrrawgk than the gaw of the American Crow), and much deeper than the Chihuahuan Raven that I heard in northern Texas. However, because it has been a few years since I had seen or heard the Chihuahuan, I decided to double check the calls on a tape I had at home. The tape and I agree that the call was that of a Common Raven. | The original documentation form event lasted from approximately 11:10:00/11:11:00.

|
Summer Tanager
|
Iowa City
|
315 S. 7th Ave. Iowa City, Iowa
|
Urban area, small back yard with several feeders and brush cover.
|
The documentation form by Thomas H. Kent is the earliest and the one that forms the basis of this record. Another documentation form by Jim Fuller was submitted later. Other observers include Mary Noble and Dick Tetrault. | Elimination of similar species: The overall coloration and plainness indicate a female or immature bird. The lack of prominent gray in the auriculars and light bill color argue against Hepatic Tanager. The bill length, head shape, and relative paleness of the wings favor Summer Tanager over Scarlet Tanager. The lack of prominent wing bars appears to exclude Western Tanager. The apparent lack of orange tint suggest a bird from the West or perhaps an immature. The Summer Tanager photographed at Pleasant Valley in Scott County on 2 December 1990 was more orange-yellow than the Iowa City bird. The latest Midwest record for Scarlet Tanager in books of these states was 26 Nov in Minnesota. There are a few winter records of Summer Tanager: in Tennessee (4) 5, 18, 21 Dec and 2 Feb-15 Mar; in Michigan 1 Dec; in Missouri 3-10 Jan 1987. There are also winter records from Florida and the Texas Coast. This does not constitute an exhaustive search for winter records. | The original documentation form event lasted from 08:10:00/08:15:00.

Cedar Lake, Cedar Rapis, Linn Co., IA
|
Large round backwater lake kept open by output from Quaker Oats Plant. The lake was half frozen two days ago, but two warm days made it ice free.
|
The documentation form by Thomas H. Kent is the earliest and the one that forms the basis of this record. | Elimination of similar species: The short legs and large rounded head with thick neck are the main features that distinguish immature Black-crowned from Yellow-crowned Night-Herons. The round white dots on the upper wing are supposed to be more prominent on the Black-crowned, but this is difficult for me to judge. | The original documentation form event lasted from 13:05:00/13:30:00.

Also, wings were held flatter than what I expect for a Turkey Vulture. Harlan's Hawk: Breast and belly solid in color, no barring on tail, wing shape unlike that of Red-tailed Hawk. Size difference.

I would have been very surprised if they had been any wren species other than Marsh or Sedge in this habitat. The combination of a white eyeline, dark mantle with thin white stripes, white throat and breast, and dark crown eliminated other wrens, especially Sedge Wren. I also recognized the chip note as that of a Marsh Wren. | The original documentation form event lasted from 08:10:00/08:55:00.

The documentation form by Stephen J. Dinsmore is the only one submitted and forms the basis of this record. Other observers include Jim Sinclair and Gordon Brown. | Elimination of similar species: The most similar species would be American Tree and Chipping Sparrows. The combination of white eyering, lack of a breast spot, and pink bill eliminates both of these species. | The original documentation form event lasted from 11:32:00/11:35:00.

The documentation form by Ann Johnson is the earliest and the one that forms the basis of this record. Another documentation form by Stephen J. Dinsmore was submitted later. Other observers include Aaron Brees and Phil Walsh. | Elimination of similar species: Yellow-crowned Night-Heron was eliminated by the boldness of the markings on both the upper and underparts of the body and by the leg extension in flight. | The documentation form event occurred at approximately 09:30:00
