Hi,

While this likely holds little interest for those only interested in
birding, The Second Atlas of Breeding Birds in Ohio, is now available from
Penn State University Press. This volume is full of useful information for
people with a more general interest in Ohio's avifauna and natural
environment.

For example in this volume you will find that the Wood Thrush, is estimated
to be the 18th most common breeding species in Ohio with an estimated
breeding population of 1.54 million individuals.  The breeding population
of Cerulean Warblers is estimated to have  declined from 118,000 to 56,000
between 1987 and 2011. The most common breeding bird in Ohio is the Song
Sparrow.

Each species account has maps showing the breeding distribution for the
species and a comparison between the first and second atlas survey rezultz.


This book is a valuable resource and offers an interesting comparison over
a relatively short time.  However it must be noted that due to differences
in methods and effort, the comparisons over time cannot be viewed as
conclusive, but still offer useful insight into changes over the 20 years
between the 2 atlas efforts; and these changes are in some cases,
astonishing.

For instance the expansion in the breeding population of Dark-eyed Juncos
in NE Ohio is of particular interest to me, and the atlas rezultz confirm
the anecdotal reports of the explosion of breeding Juncos in this region.

This atlas in no way replaces Peterjohn's Birds of Ohio, which included the
first atlas rezultz and remains the definitive contemporary work on Ohio's
avifauna. Still the atlas if full of useful information that covers not
only breeding occurrence, but also habitat, phrenology, and speculation on
future trends due to changes in the environment.
