 tip 15-19 mm.) 



Nestling. (Not examined.) 



Juvenile. Closely resembling adult but feathers of crown 

 brown-black and tips duller white, feathers of crest shorter and not 

 so pointed ; black of chin and throat brownish and some feathers 

 tipped white, black of base of throat not extending on to sides of 

 neck, and no encircling black line at base of sides of neck.

 tarsus 17.5-19, bill from skull 9-11 (12 measured). wing 59-65. 

 Primaries : 1st 9-14 mm. longer than primary-coverts, 2nd equal 

 to (or between) 8th or 9th, 4th and 5th longest, 3rd 2-3 shorter, 

 6th 1 shorter, 7th 3-5 shorter ; 3rd to 6th clearly, and 7th less 

 clearly, emarginated outer webs. Secondaries equal 10th primary, 

 tips round with somewhat pointed apex. Tail slightly forked, each 

 feather being sloped off at tip of inner web. Bill fairly strong. 

 Good many rictal and nasal bristles, short bristle -like feathers 

 covering nostrils. Tarsal joint feathered.

 Grange, Melton (Suffolk), about 1873, Suffolk, about 1840. Others 

 are recorded as seen.]
