58 The Wilson Bulletin — No. Ill 



described to me as having been observed by different persons. 

 " Nigger-boy " it is called, " because it boilers so queer." 

 Ardea herodias herodias — ^Great Blue Heron. 



A bird of this species shot January 20, 1919. measured: length 

 43% in.; wing 18^/4 in., bill on top 5 in., torsus ^V^ in., sex, c?. Dr. 

 Oberholser writes me regarding this bird: " If you have cor- 

 rectly sexed the specimen I should say that your bird is without 

 much doubt Ardea herodias licrodias from the measurements you 

 give. This form should be of more or less regular occurrence in 

 winter in Florida, but as the distinction between it and A. h. wardi 

 is partly in color I cannot be absolutely positive without seeing 

 the specimen." 

 Guiraca ccerxilea ccerulea — Blue Grosbeak. 



Mr. John Linton has on at least two occasions seen a dark 

 blue bird larger than an Indigo bird and not Sialia. sialis. As the 

 species has occurred in Loon County, next adjoining us to the north, 

 it doubtless visits us occasionally. 

 Hplocichla usHilata sxvainsoni — Olive-backed Thrush. 



On four occasions - 1 have seen birds believed to be of this 

 form, but no specimens have been taken. October 26, 1913, No- 

 vember 3 and November 21, 1913, and March 1, 1914. 



Introduced Species. 

 Passer domesticus— English Sparrow. 



While these birds have had a footing here for a good many 

 years they increase but little about St. Marks and are not gen- 

 erally distributed over the county. 



Summary. 

 The species treated may be grouped as follows: 



Residents 63 



Summer Residents 30 



Migrants 30 



Winter Visitors 97 



Casuals 14 



Extinct or Disappeared 4 



Native Species 238 



Introduced 1 



Need confirmation 5 



A few of the species listed as Summer Residents may occa- 

 sionally occur in winter. One or two given as migrants may nest 

 here rarely. The list of Casuals has been extended to include 

 some species that probably nested here formerly, may be seen here 

 in summer, but of which no record can be found for their breed- 

 ing with us in recent years.
