April 10, 2018: Wolf's March 2018 Wildlife Report



Buffleheads were present throughout the month.  This pair was found on the south lake. (Wolf. Oesterreich, 3/17/18)

A total of 71 avian species (plus 2 sp.) was recorded in March 2018, ranking this month as the 9th highest March among 21 years of records.  This total is 17 species more than last month and 5 less than March 2017.  March 2012, with 82 species, remains as the March with highest total, while March 1998, with 44 species, is the lowest. 

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 single Fox Sparrow found on the 4th may represent a new extreme early Spring record (former record set on 7th March at the State Forest Nursery in 1982 & my backyard in 2009) for Story County.

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, FY=front yard).  The order follows the 58th Supplement (2017) to the American Ornithologists’ Union Check-list of North American Birds and the 17th Supplement to the 7th Edition (1998).

Three American White Pelicans arrived early this evening, my first of the year.  Note the fibrous plate on their bills, only present during the breeding season. (Wolf. Oesterreich, 3/27/18)
