viduals seen in one day; recorded ten to fifty-nine times each year. 
April 18-May 31. August 1-October 1. 
SOLITARY SANDPIPER. A regular migrant both spring and fall. 
One to four birds have been seen per day. Observed two to seventeen 
times each year. April 26-May 16. August 5-September 20. 
WESTERN WILLET. A rare migrant seen only in 1933 and 1936; 
two times each year; one to four birds on each day. April 30-May 13. 
August 2-October 22. 
GREATER YELLOWLEGS. Spring and fall migrant, more common in 
fall. One to seven birds seen per day; recorded one to four times each 
year. May 19. August 2-October 22. 
LESSER YELLOWLEGS. A regular migrant in fall only. One to two 
birds seen each day and occuring one to ten times each year. August 
1-October 22. 
The two species of yellowlegs do not always occur under circum- 
stances that permit easy separation when seen alone, though extremes 
in size are readily distinguishable under favorable ccnditions. The 
best field mark is the bill: long and stout in the greater, shorter and 
more slender in the lesser. Considering the two species together, the 
extreme dates are August 1-October 26. 
PECTORAL SANDPIPER. Migrants come both spring and fall, but 
are more common in fall. From one to ten individuals were seen on 
each day; observed from four to nineteen times each year. April 17- 
May 11. August 1-October 24. 
This species is easily separable from any others with which it 
may be confused by the dull yellow legs. It has two “kreek”’ calls, one 
high-pitched, the other low. I have heard a single bird give both. 
WHITE-RUMPED SANDPIPER. A rare migrant in the park, seen only 
in the fall of 1936; one bird only on August 15 and another on 
October 10. One was plain gray with an unmarked back, the other 
had a “scaled” back and some buff on the breast making it resemble 
the Baird’s sandpiper. This species is easily distinguished from others 
that are similar oy the white rump and the call, a faint squeek very 
different from the “kreek” of the pectoral and Baird’s sandpiper. 
BAIRD’S SANDPIPER. A common species in the fall. One to sixteen 
birds seen each time; observed from four to forty-three times 2ach 
year. August 5-November 11. 
The “kreek” call, black legs and dark rump will separate it from 
the white-rumped; the black legs, scaled back and gray-streaked buff 
head and breast distinguish it from the pectoral sandpiper. Every fall 
I have seen some individuals that have a minimum of buff on the 
head and breast; thus they are grayer in these areas and resemble the 
white-rumped more closely. 
LEAST SANDPIPER. Rare in spring, common in fall. One to thirty 
birds seen each day; recorded three to forty-seven times a year. May 
10. August 8-October 3. 
The only least sandpiper I have seen in the spring had bright 
greenish-yellow legs. The legs of fall birds are dull olive green, but
