 consisted of the following, : — 



15 to 17 full-fed larvae of the Geometrid or Mottled Umber 



Moth (Hybernia defoliaria) ; and 2 large larvae of a 



Noctuid moth (? Triphaena). 



400. — Between 3.50 p.m. and 7.55 p.m. 25 visits were made by 

 the parent birds and the following were identified : — 



11 large Noctuid larvae (Triphaena, &c.) ; 2 Tipulid larvae 

 (probably Tipula oleracea) ; 8 to 10 Crane Flies (Tipula 

 sp., probably T. oleracea) ; bread, 3 lots ; 2 molluscs, 

 probably Zonites cellarius ; several small insects and 

 1 grasshopper were brought in on one occasion, but the 

 former were much too small to be recognised. 



401. yth June. — Between 5.15 a.m. and 12.15 p.m., with 

 30 minutes interval between 8.25 a.m. and 9 a.m., 79 visits 

 were made during the 6 J hours. The following is a summary of 

 the food which was identified : — 



25 larvae of a large species of Noctuid moths, possibly Tri- 

 phaena orbona ; 60 to 70 larvae of the Geometrid or 

 Mottled Umber Moth (Hybernia defoliaria) ; 4 green 

 Geometrid moth larvae ; 2 chrysalids (pupae) of the 

 Yellow Underwing Moth (Triphaena pronuba) ; 4 Tipulid 

 larvae ; 2 beetles, 1 a weevil, the other a small carabid ; 

 1 beetle larva (Geodephagous) ; 4 wireworms (larvae of 

 Agriotes or allied genera) ; 3 molluscs (Zonites ? cella- 

 rius) ; 2 small earthworms. Small insects unidentified 

 on 9 occasions (some were beetles and very probably all 

 were, but they were so closely packed together that it 

 was quite impossible to recognise more than one or 

 two) ; bread, 5 lots. In addition to the foregoing 8 

 different lots of food were brought in which looked very 

 like garbage from a kitchen midden, and 4 visits were 

 made without bringing in food. 



402. 8th June. — During the period between 5.15 a.m. and 

 11.30 a.m., the watching being suspended on several occasions

6 larvae of large Noctuid moths (? Triphaena spp.), ; 60 to 70 

 larvae of the Mottled Umber Moth (Hybernia defoliaria) ', 

 6 green larvae of a Geometrid moth ; small beetles and
