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 at least), when a maximum population is breeding, one hundred and 13 active nests would be present accounting for 2260 adults. At the present time the distribution is: High SW walls 8.6 % of breeding population. East Central cliff 72.4 % " " NW circular 17.0 % " " 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 20.4 % Imm. 1.7 100.0 %. R.S. Grossi 1968 Blue-gray Noddy (1) 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 are certainly not very abundant at this time. I have noted about 5 large chicks of medium chicks and about 4 or five eggs. Only a very few birds are nesting at this time. Many, however, continue to nest practically in all areas except where the rocky terrain is dense. Largest congregations, however, are nesting along the Serenian along this bayou. 25 Oct. right. An estimated 2000 birds count along SE-SW bayou shores in Serenian Pato.
