MacLean 1966 Phalaropus fulicarius 16 June to 10 June At Meade River - Density was about equal to Barrow. At this time they are easy to collect, and a sample of 8 was taken. 5 PP showed very good laying synchrony - 4/5 on 3rd or 4th egg. 5th got fouled up somewhere along the line. If PP do not remain there and flock after finishing duties synchrony would appear greater than it actually is. Saw no flocks of PP. 20 June Pairs frequently encountered in ponds among polygons west of cake-eater. If they utilize all habitat as densely as this it won't be a disastrous year. Birds are mostly feeding. They obviously use visual clues, and the return as indicated by frequency of feeding motions during active search seems low. (Not, methinks, as low as Meade River, where they were really working for a meal.) In ponds South of Gasline Pipe - nothing. Guess they won't utilize habitat uniformly. That should be a good area. 21 June In Voth Area South of Creek - saw PP phalaropes beginning to associate. Saw a group of 4 flying
