SAP SUCKERS AND THEIR GUESTS. 143 



to Orchard No. 2. During tlie nine hours tlie 

 male paid ten visits to the tree, the female four 

 and the young one three. Forty-one visits were 

 made by humming-birds; in several instances 

 two were in the tree at once. The tree swarmed 

 with insects, mainly large flies. One or more 

 butterflies came. Early in the morning, I added 

 brandy and sugar to the maple syrup in the cup. 

 The humming-birds with one exception dipped 

 only in the drills. In one case a humming-bird 

 drank for sixty seconds (including a rest of ten 

 seconds) from the cup. He then flew away. 

 The young sapsucker dipped only from the drills, 

 the female dipped thirty times or more from the 

 drills, and twenty-five times from the cup. The 

 male dipped fifty-four times from the drills and 

 worked a little in deepening holes, drank sixty-six 

 times from the cup and caught twenty insects, 

 some on the wing, some on the edge of the cup. 



I noticed with surprise that the humming-birds 

 in more than one instance took sap while clinging 

 to the bark with their feet, their wings being at 

 rest. I have been told by a careful observer that 

 they cling to the trumpet flower in the same way 

 while crowding themselves into its mouth to draw 

 its sweets. 



My notes refer again and again to the spite- 

 ful treatment of the hummers at Orchard No. 1. 

 On the other hand, at Orchard No. 2 they say,
