R.S. Grossin 1768 Bulwer's Petrel 20 Oct. Lyclean Island Bulwer's Egg Measurements 44.3 x 28.6 42.6 x 30.0 39.4 x 28.9 39.0 x 29.7 39.2 x 30.0 39.8 x 28.6 44.3 x 31.0 37.4 x 29.1 Summary Candled 33 birds and recovered 3 - one of them yielded thus dead 35 candled individuals. Of these 6 were known pairs, possibly a few more pairs at least deaded embryos. The pairs were: 1103-07080-81 84-86 112-572 60-61 62-63 712-57277 79-80 At least 10 nests were found with fresh to slightly incubated eggs and one with a small living young. On other eggs which hatched during the stay making at least two with chicks upon departure. Two of the known pairs, was calling from empty nest cavities and pre- dug from empty nest cavities in pockets. Practically 100 % of all birds were first detected by hearing them call from the nest cavity, no matter what the postures. R.S. Grossin 1768 Bulwer's Petrel Lyclean Island Summary Thus during October in combination this resulted a probe in nest finding and egg laying. A few birds, just shy in the film of 4 % had already laid 1 offspring and either (this concerns only those birds banded). If one considers all the birds, 5 day out which were not, banded, this figure probably places to fields 5% having already laid eggs and October. All along the major paths con- cerning along the main W side & NW, Bulwer's were in ample abundance. In the most past positive detection could not be made due to do screening Eggy, holly & the grey middles along much of the well & rock pile area - never first the birds heard from vague areas in these areas were actually day out. In the still standing walls, most birds could not be dug out without harry down the entire wall. A few times I attempted to scrape some sort of loosely figures on the birds, but this is almost impossible. It was custom- common for 3 or 4 birds to be heard calling from a few square feet in many areas, 7 walls or huddled down rock areas. A very conservative estimate of the island population would be 1000 birds - possibly many more. at the end 7 October I estimated 5 % a few had small to medium living chicks; 36 % were on eggs and 67 % were either settled or inspecting nest sites.
