Estimates given are the largest during the period I96O-I969 except for those 
vhich vere specifically noted as probably erroneous in the Laysan Account. Tliese 
estimates are occasionalj^y included here 'within brackets. When the maximum 
estimate for a given species -was reported as a’range (e.g. 3 , 000 - 4 , 000 ) the higher 
figure is utilized here. Maximum recent estimates are of the maximum number of 
flying birds on the island during any one visit unless other vise indicated. 
Maximum recent estimate of breeding populations is the maximum estimate for any 
one recent survey. For some species (e.g. Black Noddy) annual breeding populations 
may exceed maximal estimates for sny one survey. In nearly all instances here 
breeding population is equated vith tvice the number of nests (vhich can be 
interpreted as the estimate of the number of eggs and dependent young, that have 
.clearly not fledged.) By conventional definition of’'breeding population" (say 
for summer cycle, species) both spring and fall estimates are thus biased low, 
the former because paired, courting and/or territorial birds are not allowed 
for; the latter because the number of birds vhich may be feeding fledged young 
(and hence are clearly part of the breeding population) was probably never aHoved 
for.

Figure is believed excessivlly large. 
Estimate is from Kenyon and Rice aerial estimate in 1957 . Kenyon (pers. comm. ) 
agreed, after having seen populations on the ground, that some of the albatross 
breeding population estimates in Rice and-Kenyon, I962, were likely excessive. 
This estimate may be excessive but is not certainly so. 
Indicates an estimate next highest to one listed above. 
$ 
Conceivably somevhat high but populations certainly on the order of 500,000 
birds and up. 
Numerical "translation" of estimate of "a few" in Clapp 8 c Wirtz. I would 
definitely not include as a presently breeding species. We looked liard for 
them in Sept, I967 (when young wo'uld be most conspicuous) but found no 
trace. I would treat this species as an extirpated breeder until good 
evidence to the contrary is shown. Possibly or even probably the Sooty 
Storm Petrel once bred there as well. 
Estimate may well be erroneous, but is probably more comparible with 
Laysan figure than next highest estimates would indicate. Three thousand 
may be fairly reasonable. 6OO islikely low for a maximal breeding 
popul ation. 
Probably Laysan Teal (?) but not cor'balnly so. Newspaper account strongly
