DISTRIBUTION OF OUR BIRDS IN SPRING 15 
DISTRIBUTION OF OUR BIRDS IN SPRING. 
BY BROTHER ALPHONSUS, C. S. C. 
In four springs, the Blue Jay was least abundant in March, 
there having been a total of 72 records for that month. In the 
same period, there were, 111 records for April and 113 for May. 
A comparison of the totals for each spring shows considerable 
disparity. Between the highest total and each of the others there 
were respectively 6, 18 and 30 records. The total number of 
records for the four seasons was 306, the species not having heen 
observed on 62 days. 
Unlike the Blue Jay, the Crow’s records in four years, show 
a decrease from March to May, the totals for the three months 
being 101, 93 and 76 records. The various totals for each year 
show successively differences of 18, 29, 23 records fewer than the 
highest total in 1910. There is a very slight difference between 
the records of 1911, 1912, 1913, 11 records being the highest 
and 5, the lowest. The total for the four seasons was 270 records, 
The Snowbird, for four years, was most abundant in April, 
the total number of records for that time having been 104. For 
the same period, March shows 71 and May 5 records. In March, 
the species was most unevenly distributed, as the number of 
records for four years shows—27, 14, 9, 21. In thé totals for each 
of four seasons, the greatest difference was 16 and the smallest, 
5 records. The total for four springs was 18o records. 
The Bluebird presents records that are exceptional in one 
year—1g912. The total for the spring of that year was 17 records, 
which was 28 fewer than the lowest total of any of the other 
three years. For four springs, the species was most abundant 
in April and least plentiful in May. Leaving out the records for 
1912, and there is but a slight difference in the totals for March 
and April, 63 records for the former and 7o for the latter. Making 
a comparison, without the records for 1912, we find the various 
totals for the other years showing 29 records as the greatest differ- 
ence and 19 as the least. The total for four years was 191 records. 
The Robin shows exceptional irregularity in March, 1912—, 
there being only 9 records for that month. Barring this exception, 
the species is a typical example of great regularity in all the spring 
months. In March, 4 records was the greatest difference, and 2
