he former being stationary with the latter, which is said to be a 

 migratory species. 



The Rev. Mr. White formerly hinted to us his opinion, of the two 

 synonyms above quoted from Brisson, only differing in sex. He 

 adds, that they are found throughout the year in abundance in all 

 parts of the Rock of Gibraltar, especially the retired places ; are 

 solitary, and seldom come into the town ; that the male is a much 

 finer songster than the Redstart, from which bird, too, it differs in 

 manners, for it never leaves the district, whilst the Redstart migrates 

 elsewhere. Some have supposed the Redtail to be the same as the 

 Moretto Warbler ; but Mr. White informs us, that having sent both 

 sexes to Linnaeus, he declared them to be different from the latter, 

 which he recorded in his 10th Edition, under the name of Tithys. 

 Notwithstanding the opinions of the authors above quoted, in respect 

 to this and the last bird, we are inclined to think them the same as 

 to species, with the plumage more or less mature.
