Durine the months of March, April, and May the members of 
the club are going to carry on organized observation of the spring 
migration. ‘The system that is going to govern the observation is 
simple. ‘The plan is to have at least two, usually more, fellows in 
the field every afternoon from March 1st to June Ist. All the best 
bird territory about Boston will be covered in this way as often as 
possible. So that each piece of ground may get good attention, each 
fellow will be given a weekly assignment of country to cover, and 
will hand in a weekly report of all birds seen by him, giving date of 
Ist arrival, when the bird was next seen and when it became com- 
mon. In this way it is hoped to study the spring migration closely 
and accurately. If sufficient interest is taken, the same plan will 
be applied to the fall migration. 
All results will be published in The Wren. 
NOTES. 
One of the many birds spending the winter north of their winter 
range is the Catbird. One of these birds has been seen near the 
administration building in the Arboretum by numerous observers. 
It was first seen November 22 by Barron Brainerd, Joseph Kit- 
tredge, Jr., and Charles Schweinfarth, and last seen on January 
17 by J. L. Peters. On December 13 one was seen in some thick 
bushes near the foot of Hemlock Hill, but may have been the 
same bird.
