564 MICHIGAN BIRD LIFE. 
At Greenville, Montcalm county, the late 
Percy Selous recorded a nest with eggs April 
23, 1894, the young becoming full-fledged on 
May 25, while the same pair (presumably) 
brought out a second brood on July 26. Dr. 
Gibbs records fresh eggs from Kalamazoo county 
April 18, 1878, April 27 and 30, 1879, and 
others were obtained on May 18, 1880, and June 
22, 1878. The late Richard B. Westnedge, of 
Kalamazoo, took six eggs from a nest May 26, 
1888, and six from another nest June 5, 1892. 
In that part of the state the nests seem to be 
placed as often in osage orange hedges and 
neglected orchard trees as in thorn trees. The 
eggs vary in number from five to eight, but ne 
are ordinarily six or seven, and are hardly Tail of te cnt AG. 
separable, except by size, from those of the e 
Northern Shrike already described. The average given by Ridgway for 
the typical Loggerhead, the southern form, is .97 by .73 inches, but speci- 
mens of migrans in the college collection average nearly 1.00 by .75 inches.

TECHNICAL DESCRIPTION. 
Bill strongly hooked, wing less than four inches, tail shorter than wing, third and fourth 
primaries about equal, the third usually a little longest. 
Adult (sexes essentially alike): Upper parts ash-gray to blue-gray, usually paler 
(sometimes whitish) on rump and upper tail-coverts; forehead commonly paler than the 
crown; under parts mainly pale ash-gray, deeper (almost the shade of the back) on chest 
and sides; throat and belly nearly or quite white; markings of head, wings and tail, and 
colors of bill, feet and iris, precisely as in the Loggerhead; the young also are similar to those 
of that species.

3.60 to 3.90, of female 3.60 to 3.78; culmen about .53 (Wm. Palmer). 
Family 61. VIREONIDA. Vireos or Greenlets. 
A small family of interesting and valuable birds, represented in Mich- 
igan by half a dozen species which are so similar in size, color, voice and 
habits as to be readily confused by the beginner. The following key 
will help to separate them:
