RS Brown 1768 Hawaiian Noddy 20 Oct. Culmen measurements of different age classes. (mm.) SDY MDY LFY 12.4 17.9 23.1 12.5 17.5 24.6 15.8 22.5 25.5 14.4 24.4 27.4 11.0 24.7 29.0 24.3 Individual variation in bill length possibly accounts for the overlap in Categories MDY and LFY. 24 Oct. This was with a complete count of all nesting areas of this species we have a total of 58 active nests, plus an additional 55 old nests. If new nests are not constructed (or very few of last), when a maximum population is breeding, one hundred and 13 active nests would be present accounting for 226 adults. At the present time the distribution is: High SW walls 8.6 % of breeding population. Large Central Ledge 72.4 % " NW circular 19.0 % " Plus at the time of the survey, the breakdown for breeding areas. Eggs - 58.6 % of breeding population: SDY 8.6 " MDY 10.4 " LFY 20.7 " Eggm. 1.7 100.0%. RS Brown 1768 Blue-grey Noddy McLean Island Egg measurements: 40.6 x 25.7 Culmen Measurements 17.5 LFY 17.6 LFY 15.4 MDY 24 Oct. Eggs are very difficult to find of this species and as certainly not very abundant at this time. I have noted about 5 large chicks, 4 medium chicks and about 4 or five eggs. Only a very few birds are nesting at this time. Many birds, however, continue to roost practically in all areas except where the rocky terrain is dense. Largest congregation, however, are roosting along the Ternarium along the bayon. 25 Oct. right. An estimated 200 birds count along SE - SW bayon shores in Ternarium plate.
