Then the kingfisher remained squatting on the bank for a couple of minutes looking pensive. This was scarcely to be wondered at, seeing that as regards size the frog bore to him the same relation as a large mackerel does to a man. I was interested to see whether the kingfisher would consider this a sufficient meal, or whether he would immediately resume his fishing operations. I expected him to adopt the latter course, for birds have most voracious appetites. If horses were to eat in the same ratio they would require at least a maund of oats per diem to keep them in health! My surmise was correct. In a few seconds the kingfisher flew to a large stake projecting from the water and squatted there, cocking up his tail at frequent intervals. This motion of the tail is possibly an aid to digestion! When he was thus seated, the tern reappeared on the scene and at once recommenced fishing in the manner already described. After the tern had been fishing for a couple of minutes the kingfisher resumed operations and again sought the neighbourhood of the ducks. He soon captured a second frog; but this time, instead of being able to bear it to the bank and devour it in peace, he had to reckon with the tern. He had not risen a yard above the water when the tern noticed that he had quarry. Forthwith the tern committed a breach of the tenth commandment and then proceeded to try to violate the eighth. He made a swoop at the kingfisher, which the latter adroitly dodged, squeaking loudly but without dropping the frog. Then ensued a chase which was a sight for the gods. As regards pace on the wing the kingfisher is no match for the tern. In an aerial contest the slower flier has the advantage of being able to twist and turn more quickly than the rapid flier. Of this advantage the kingfisher availed itself to the full, so that the contest waxed fast and furious, the combatants moving in a series of curves, zigzags, circles, and other geometrical figures.
The kingfisher, notwithstanding that he had just swallowed a frog, evidently had not the least intention of delivering up his catch. The tern appeared equally determined to capture it. Seeing that he would never be able to enjoy the fruits of his prowess while he remained at the tank, the kingfisher changed his tactics and flew right away, disappearing behind some trees, with the tern in pursuit. The latter, however, did not follow far. He seemed suddenly to come to the conclusion that honesty is the best policy, and returned to the pond to endeavour to secure food in a more legitimate manner. I waited on for about half an hour, expecting to see the kingfisher reappear, but was disappointed. Then the tern went to seek pastures new, and left the ducks and a solitary wagtail in possession of the tank.
