GAIRDNER'S WOODPECKER. 



The Ramping Trumpet-flower. 



BlGNONIA CAPREOLATA. 



This species is met with only in the Southern Districts. It is rather rare 

 in Louisiana, but abounds in Georgia, Alabama, and the Floridas. The 

 flowers are destitute of odour. Humming-birds delight to search for food in 

 them, as well as in those of other species of the genus. 



GAIRDNER'S WOODPECKER. 



f 



Picus Gairdnerii, Jiud. 



(Not figured.) 



This curious little Woodpecker is so very similar to Picus pubescens in 

 form, size, and colour, that one can scarcely distinguish it, its affinity to that 

 species being as strict as that of Picus villosus to P. canadensis. Its bill 

 is slightly stronger; but the greatest difference is found in the toes, which 

 are very much larger, as will be seen from the following measurements. 



Tarsus, 

 Hind toe, . 

 Its claw,

 Third toe,

These differences may appear slight, and were there intermediate grada- 

 tions, would be of no value, but I find that eight individuals of P. pubescens 

 present no material deviation from the above measurements, while my 

 specimen of P. Gairdnerii may be at once distinguished by the greater 



Picus Gairdnerii.
