All:

The Bermuda Petrel (Cahow) story as concerns Nova Scotia - including a  
spring sight record by a CWS employee on the Scotia Shelf - will be  
covered the seabird writeups by Eric Mills in the next issue of "Nova  
Scotia Bird" - another good reason for belonging to the Society for  
its modest fee. It must be kept in mind that the results from data  
loggers (which give daily estimates of sunrise and sunset, from which  
positions can be approximated) can be pretty unreliable - 100s of km  
off. The conclusion that one or two reached the Gulf of St. Lawrence  
may be dubious, and the inference that young come here routinely to  
feed on krill is speculative.

Also, the following statements may be inaccurate:

    "We were suspicious when we got the first tags back, so we put the  
word out to Canadian fishermen and others in the northern regions  
where the cahows were being logged. . . They duly received reports  
that they were occasionally being seen in those areas. . . We thought  
the bird might have been confused with other petrels. But when we got  
a photograph, it was unmistakeably a cahow. So we know, every year,  
they go up to Canadian waters."

    I believe the photo referred to was actually taken during a marine  
mammal survey along the shelf break of Georges Bank, about 6 km s. of  
the Canadian Boundary. The link to "Canadian fishermen and others in  
northern regions" may be dodgy. The "Others" referred to may the CWS  
observer and the U.S. marine mammal surveyer.

    That is not to say that Cahows don't wander here - the combined  
evidence is strong. But how many, how often, and why are not yet clear.

Cheers, Ian
