Texbirders: Found the linked article about breeding birds during 1910-14 in Harris County quite interesting. He sighted a few species not currently found in the county Bachman's Sparrow Apr 25, 1911 approximately where san jacinto battelground is now Red Cockaded Woodpecker May 25, 2012 in pine woods on Buffalo Bayou, about eight miles west of Houston (see map at bottom) 14 Greater (Attwater's) Prairie-Chickens June 7, 1913 Aldine, at side of railroad tracks Here's the link http://www.bayoupreservation.org/html/Birds.Trees.Harris.County.1915.pdf Here's a map from that time period. I think he may have used something similar to the following map to calculate his distances from city of houston when taking his rail journeys as this map has concentric circles measuring distances from the center of Houston (courthouse) and GF Simmons uses this same method of measurement for each oif his breeding bird sightings http://www.harriscountytx.gov/archives/Img.aspx?img=13 Using the article, this map and a modern day map, I have entered a few of Simmons key sightings from the article into ebird here http://ebird.org/ebird/tx/sightings?listType=first&locInfo.regionType=subnational2&locInfo.regionCode=US-TX-201&beginYear=1900&endYear=2012&continuous=true&sortBy=obs_dt Other interesting early Harris County reports (not in Simmons report) Ivory-Billed Woodpecker June, 2013 by Clifford Shackleford (reported in Olberholser 1974 and in in Bulletin of Texas Ornithological Society 31(2) 1998 p.37 ) http://www.houstonaudubon.org/html/IBWShackelford.pdf John Berner West Houston/Katy
