were laid, but they all proved clear. Why they should 

 all be clear I do not know. I have never seen the 

 birds pair, though I have seen them feed each other. 

 I have an idea that Psittaais and Pceocephalus do not 

 reach maturity for some time. So often one sees 

 something like this in Bird papers: "My Grey Parrot 

 has laid an ^ZZ- I have had her 17, 18, or 20 years" 

 (as the case may be) " and she has never done it 

 before. Is this unusual ? " 



When I bought my Pceocephali they all seemed 

 nestlings, except the one that has laid, which looked 

 very old ; and I ask myself was the bird I supposed to 

 be a cock (these two had consorted together when I 

 had the five loose in an aviary) too young to mate ? I 

 throw out the idea for what it is worth and only 

 narrate my experiences, because all our real know- 

 ledge is founded on a structure of these small facts 

 put together. 



It is noticeable that whereas Pala:or?iis cyanocephala 

 never, according to my experience, attempt a second 

 clutch of eggs, but proceed at once to moult, this 

 Pceocephalus laid again and again. 



It is rather unfortunate that my tamest Pceoce- 

 phahcs never develops its flights. When I first bought 

 them, I thought it and several others were pinioned, 

 but I found they were not. However, this bird, though 

 it has the joint, never develops perfect feathers from 

 it. If it had flights, I could trust it loose. Another 

 recommendation for the Senegals is, that they are as 

 easily kept as a Grey. They only want hemp, canary, 

 and millet with an occasional monkey nut. I also 

 give them bits of oat cake and they are very fond of 

 sow-thistles, groundsel they do not care much about.
