conditions when the temperature is above 10 degrees Celsius and the humidity is high. The same conditions when windmills must operate at highest efﬁciency. The ﬂying insects do the same to the windmill blades as they do to a car windshield - they create a ﬁlm of remains on the surface. The impact can be a substantial reduction in energy conversion.

The first test of the protection of the Bald Eagle under the Ontario Endangered Species Act occurred in the Ontario Court of Justice on Nov. 8, 2001. DeCarolis Farms pleaded guilty to destroying

endangered species habitat (cutting down an eagle's nest). The company was fined $5,250. (adapted from 880 Latest News from BSC)

HILLSBOROUGH PIER PROJECT: report by Bruce Smith

The Common Tern population in Atlantic Canada has been declining for over a decade. After an unsuccessful experiment with the use of exclosure wires installed around the tops of each pier to stop the nesting of the Great Black-backed Gulls, the Natural History Society began the removal of the eggs of those Great Black-backed Gulls nesting on these piers. Great Black-backed Gulls are predators of the terns, eating both eggs and young terns. In this way, they were destroying almost all tern production in this nesting site. Early this year, Great Black-backed Gulls were nesting on piers # 3 and 4.

On May 30th, under a special permit issued through the Canadian Wildlife Service, representatives of the Society removed three eggs from a nest on piling #3 and two from a nest on piling #4. It was interesting that a partially eaten tern egg was found on piling #4 next to the nest. This piling has two nesting levels with the gull nest on the top level. On the lower level, there was at least five tern nests. Three of these tern nests had a single tern egg while two nests had two eggs each. Thus, Common Terns were attempting to nest on the same pilings as the Great Black-backed Gulls. This may be a function of a lack of nesting areas for the terns as the grassed areas of the piers are getting reduced rapidly by the deterioration of the pilings.

As is often the case, the gulls started new nests. This time the nests were on piers #3 & 6. Both nests contained two eggs and neither piling had terns nesting on them although #6 has a ﬂat step

covered in grass which should have been conducive to tern nesting. These eggs were removed on June 26th.

WEATHER EVENTS:

An one metre storm surge combined with extremely high (120 km+ at East Point) northwest winds caused surprisingly light damage along the eastern half of Prince Edward Island on Nov. 7th & 8th. Some sand dunes were breached at North Lake and there was damage to roads at Savage Harbour and Brackley, damage to a cottage at Savage Harbour, and damage to wharf infrastructure at

Tracadie. The ﬁrst heavy wet snow hit most of the Island on Nov. 11 but temperatures ranged up to the teens in late November.

P LANTS:

This fall there is an abundant crop of Showy Mountain Ash berries in the hedgerows between Rice Point and Argyle Shore. In some areas along the north shore there are good crops of false holly berries. Water lobelia and Juncus militaris were found in Long Pond at Greenwich by Island Nature Trust staff. Some white clover and daisy ﬂeabane were in ﬂower at Hampton on Oct. 26 (WFB, JDM).
