 produce of  the  shore.  This  certainly  was  not a  case of  
 fear, for I  have  repeatedly  observed,  in  cases of  hostile  
 encounter  between  these  two  species,  that  the  Herring- 
 Gull  has  almost  invariably  proved  the  victor.  
 This  Gull  is a  hardy  rover,  and  seems  to enjoy  
 battling  against a stiff  breeze  at  sea.  In  common  with  
 other  Gulls  it will follow  ships  to  great  distances from  
 land;  but  in  this  respect  is  not,  in  my  experience, so  
 persistent  as  the  Kittiwake.  With  plenty of  room for  
 exercise,  plenty of food,  and  opportunities for  frequent  
 washing,  these  and  most of  our  other  British  Gulls  may  
 be  kept  in  captivity for  many  years,  and will  rear a  
 brood  annually.  At  Lilford  an  old  male  Herring-Gull  
 paired  with a female of  the  Dominican  Gull (Lams  
 dominicanus),  and  took  his  turn  upon  the  eggs, from  
 which  two  or  three  young  were  reared  year  after  year  
 for a  considerable  period;  the  produce of  this  pair,  
 after  going  through  the  mottled  stage,  in  which  they  
 could  not  be  distinguished from  purely  bred  Herring- 
 Gulls of  the  same  age,  acquired a  mantle  only  slightly  
 darker  than  that of  their  male  parent. I  must  here  
 mention  that  the  mantle of  the  adult  Dominican  Gull  is  
 very  much  more  truly  black  than  that of  the  Lesser  
 Black-backed  Gull.  These  hybrids  have  never  paired  
 inter se  or  with  any  other  Gulls  at  Lilford,  or,  so far  
 as I  know,  shown  any  disposition  to  nest.  The  
 Herring-Gulls  are  very  clamorous,  and  occasionally  very  
 savage  when  their  nests  are  approached;  but  although  
 I  have  frequently  seen  them  stoop  to  within a few
