The Alma College Bird Observatory is operated by Mike Bishop of the Alma College Biology Department. The ACBO operates from April through October banding breeding birds and transient migrants as well as conducting directed studies of various breeding and overwintering species. The Vestaburg Station is located in Vestaburg, MI about 16 miles west of Alma. It is situated at the Alma College Ecological Station. The station is 186 acres of mixed hardwood forest, old fields, willow marshes and a relic boreal bog and lake. The Chippewa Nature Center Station is located at Dragonfly Marsh on the property of the Chippewa Nature Center near Midland, MI. It is approximately 96 acres and is a mixture of old fields, young forest and a large mitigated wetland.

Banding at Vestaburg Station, ACBO


Wow, it don't get much slower than this!  We had a total of six birds of five species of which four were new and two were recaptures.  All of the new birds were young of the year (HY) and the two recaptures were both originally banded last year.

This time of the summer both the young and adult birds are experiencing various stages of molt and the young birds are wearing unusual juvenal plumages.  Consequently they often look pretty ragged.  This morning's birds were no exception.  Let's see if you can identify some of them.  Answers at the bottom of the page.








The coolest thing we saw wasn't a bird but an insect.  We noticed a metamorphosing cicada had climbed onto our banding table while we were working.  So we transferred it to a nearby hawthorn tree and watched as it slowly emerged from its exoskeleton as a new adult cicada.  This is the Annual Cicada, not the periodic species.  These emerge every summer after having spent one to three years (depending on the species) underground.





You can see how its wings unfurl as it pumps blood into them.  Over the rest of the day its exoskeleton will harden and darken until it is durable enough to fly into the trees and begin its monotonous afternoon serenading we listen to this time of year.

Here's the catch::

Wood Thrush  1 N
Gray Catbird  1 N
Ovenbird  1 N,  1 R
Field Sparrow  1 R
Northern Cardinal  1 N

Our next banding date for the Vestaburg station will be the week of August 9.  I will send out an announcement closer to the time.

Bird #1 - Ovenbird
Bird #2 - Northern  Cardinal
Bird #3 - Gray Catbird
