12 SMITHSONIAN MISCELLANEOUS COLLECTIONS VOL. I45 



left side without the head ; a right tarsometatarsus, complete. The 

 humeri are not a pair as they differ slightly in size. 



There is one Pleistocene record for this species from Florida. 

 Dendrocopos puhescens (Linnaeus) : Downy Woodpecker. 



One : A right humerus with the distal end missing. 



This is the first ancient record for this species. 



Family TYRANNIDAE: Tyrant Flycatchers 



Sayornis pJioebe (Latham) : Eastern Phoebe. 



Three individuals : Two right humeri, and another from the left 

 side, all complete. Slight differences in size indicate that each bone 

 comes from a separate individual. The occurrence of this species is 

 one that would be expected from its habit of placing its nest on 

 sheltered projections on rock faces. 



The record is the first one for this bird in ancient time. 

 C onto pus virens (Linnaeus) : Eastern Wood Pewee. 



One : A complete left humerus. This agrees with the wood pewees, 

 and is listed as above on geographic grounds. 



It is the first report of this group in prehistoric time. 



Family IIIRUNDINIDAE : Swallows 



PetrochcUdon pyrrlionota (Vieillot) : Cliff Swallow. 



Eight or more individuals : A series of humeri that includes 

 two complete and two fragments from the right side, and four com- 

 plete and three additional segments from the left. 



The humerus in this species is approached in size among our 

 smaller swallows by the tree swallow, but has the head slightly larger 

 and the shaft heavier. The other species concerned are all distinctly 

 smaller. 



The relative abundance of bones of this species compared to those 

 of other of the small birds indicates a nesting colony, a supposition 

 that appears to be verified by one bone with the porous structure of 

 the head typical of immature individuals not fully grown. 



Cliff swallow bones are reported from the Pleistocene of California. 



Family CORVIDAE : Jays, Magpies, Crows 



Pcrisoreus canadensis (Linnaeus) : Gray Jay. 



One : A right tarsometatarsus with the trochlea for the fourth 

 digit missing, but otherwise complete. More slender form, greater 

 outward slant of the external face of the talon, relatively smaller
