Suggestions to the Birder / Shorebirds and Sewage Ponds (p. 5)


Some additional comments about sewage ponds:


• The best and most accurate on-line source for locating sewage ponds (and just about everything else) is Google Maps. These maps are based on satellite photos, which were not readily available in 2002, and this guide's original directions to some ponds often had to rely on less accurate sources. Accordingly, corrections to some directions have been necessary, and, with the help of Google Maps, dozens of other sewage ponds not included in this guide in 2002 have been located. (Note, however, that Google Maps are not infallible: they are subject to human error when streets and roads are labeled, and a sewage pond can appear or disappear after the satellite photo of the area was taken.)

There is a new and very useful tool on the M.O.U. website showing maps of all Minnesota sewage ponds; see 1) select the Satellite and Sewage Ponds overlays (you can disregard the species at the top of the side-bar); 2) check the Sewage Ponds expand-menu box; 3) click on the town name in this menu, and zoom in on the map as needed to see the pond. (Please note that this compilation of sewage ponds includes entries for several non-municipal ponds and for some which are now non-existent or being phased out of use; these are not included in the checklist.)


• Keep in mind that most sewage ponds are not worth going too far out of your way for: many are too small to attract that many birds, very few are consistently good for shorebirds (they tend to be better for ducks, grebes, gulls, terns, and swallows), and some are hidden behind berms and fences and impossible to see without venturing beyond those fences or without permission to gain access. On the other hand, however, almost all sewage ponds can be worth a look if you happen to be in the vicinity, especially in areas where there are few other wetlands to attract water birds.

• See for a current list of Minnesota's known sewage ponds.

The MOU Records Committee now recognizes a total of 447 species recorded in the state. Since the publication of A Birder's Guide in 2002, additions to the state list have been: Cackling Goose, Mottled Duck, Tufted Duck, Inca Dove, Mexican Violetear, Costa's Hummingbird, Limpkin, Sharp-tailed Sandpiper, Black Guillemot, Long-billed Murrelet, Slaty-backed Gull, Elegant Tern, Gull-billed Tern, Northern Fulmar, Wood Stork, Brown Pelican, Roseate Spoonbill, Acorn Woodpecker, Tropical Kingbird, Cassin's Kingbird, Cassin's Sparrow, and Lesser Goldfinch. In addition, Thayer's Gull (lumped with Iceland Gull) and Black Phoebe have been deleted from the list. As of 31 December 2021, 313 species are classified as Regular, 41 Casual, 90 Accidental, 2 Extirpated, and 1 Extinct; see for the annotated Minnesota checklist with the updated nomenclature and sequence.


A partial list of additional ID reference books (see p. 15) since the 2002 publication of this guide:


• A second edition of The Sibley Guide to Birds was published in 2014. 

The Sibley Field Guide to Birds of Eastern / Western North America (Eastern guide includes Minnesota; smaller and

  more portable than original Sibley Guide, with much material omitted; second editions of both Eastern and Western

  guides were published in 2016).

National Geographic Society Field Guide is now in its 6th edition (includes several significant improvements over the

  previous edition).

The Crossley ID Guide: Eastern Birds (a unique and impressive guide, but may be of limited usefulness; includes 660

  species and about 10,000 (!) of Crossley's photos; guides to Waterfowl and Western Birds soon to be published).

Kaufman Field Guide to Advanced Birding (2011; an expanded version of Kaufman's 1990 guide of the same name).

Identify Yourself: The 50 Most Common Birding Identification Challenges by Thompson et al. (similar in concept to

  Kaufman's Advanced Birding guide).

Birding by Hindsight: A Second Look at Bird Identification by Eckert (Stone Ridge Press, see a

  compilation of the series of 70 "Birding by Hindsight" articles; also see:

Raptors of Eastern / Western North America by Wheeler (two large and expensive volumes greatly expand on material in

  the two Clark & Wheeler guides).

Hawks from Every Angle; How to Identify Raptors in Flight by Liguori (recommended guide from 2005 to 19 widespread

  North American species, with 370 photos).

Hawks at a Distance by Ligouri (a 2011 guide which updates and expands on Hawks from Every Angle ).  

The Crossley ID Guide: Raptors, co-authored with Ligouri and Sullivan (similar in concept to Crossley's Eastern Guide,

  covering all 34 raptor species in the U.S.).

Shorebirds of North America: The Photographic Guide by Paulson (more inclusive and useful than Paulson's other

  shorebirds guide).

The Shorebird Guide by O'Brien, Crossley, and Karlson (new and recommended photographic guide to all species

  recorded in North America; includes 870+ photos and extensive text).

Shorebirds of North America, Europe, and Asia by Message and Taylor (illustrated with paintings, not photos; includes

  non-North American species).

Gulls of North America, Europe, and Asia by Olsen & Larsson (printed in 2003 with many errors, withdrawn by

  publisher, corrected and republished in 2004; far more comprehensive than Grant's gulls guide).

Gulls of the Americas by Howell and Dunn (as comprehensive as Olsen and Larsson’s 2004 gull reference, and this

  newer guide is more user-friendly).

North American Hummingbirds: An Identification Guide by West (published in 2015, and probably comparable to

  Howell's and Williamson's hummingbirds guides).

The Warbler Guide by Stephenson and Whittle (more comprehensive with more features than the 1997 warbler guide by

  Dunn and Garrett).

Sparrows of the United States and Canada: The Photographic Guide by Beadle and Rising (recommended supplement to

  Rising's other sparrows guide).

Tanagers, Cardinals, and Finches of the United States and Canada by Beadle and Rising (a useful photographic guide

  similar in design to the sparrows guide by these same authors).

Although the 4th edition of A Birder's Guide to Minnesota (published in 2002) is now out-of-print, this collection of corrections and additions has been updated as needed to provide those who use this reference to Minnesota's birding locations with the most accurate and up-to-date information available. (Please note that these are corrections to the previous 4th edition – not the 5th; that new edition is currently at the printer, with publication likely this August or September.) Because publication of this edition is pending, these corrections and additions for the 4th edition have not been updated regularly in the past year as they had previously.)

Accordingly, please contact the author with new information you are aware of so this can be passed on to other Minnesota birders: either by e-mail (, or by phone (218 349 5953).
