T. Coele 1959 31 May General Account cent for studying the effects of the pattern and variable in the break-up and spring there of mews on the local diptera bretain and concentrations of lewly-esp. reptur focal - from year to year. The birds arrive on a rather fixed schedule but meteorological events vary in wide extremes from one year to the next. In a late year such as this, the birds must concentrate in those areas that tend to their earliest-as for instance the Colville dell to this year. In early thawing years there is probably less of a conceltra- twiz effect. This is and my postulare which could work for studied with the facilities at ARL.
