Index of Subjects Hi Lance and others interested, I suppose that I know as much as anyone does about the Mount roost. I first noticed the large number of crows in early evening during the winter of 1987-88 or so. I did not keep any records of numbers of birds using it in these early days but "counting the crows at the Mount roost" is the last thing we now do on the Bedford-Sackville CBC, so I do have recent numbers. Our most recent "guesstimate" was 6300 birds (28 December 2007). Last year's estimate was 8500 and the year before that was, I believe, 5800. It is likely, given the difficulty of estimating numbers under these conditions, that these numbers may be the same within "experimental error". These numbers however are considerably higher than those estimated in the late 1990's and early 2000"s. I will dig out the data which I have both to satisfy my own curiosity and yours. Regarding how far these birds might disperse during the day, I have only anecdotal information. They certainly come across the Basin and from Bedford. They also have been seen flying in the direction of the city from the airport. However, there may be other roosts around the city of which I am unaware. For example, one late afternoon/early evening I noticed numbers of crows flying WEST across Parkland Drive, rather than EAST towards the roost. At one point some years ago I tried to collect information using this forum about other crow roosts in and around the city but the response was minimal, so perhaps there are few others nearby. If I am successful in getting more information, I will post another message. Best wishes to all for a very Happy New Year.
