The frequencyof occurrenceof helpers, their age and sex, and certain behavior at nests were investigated in Azure-winged Magpies, Cyanopica cyana, living in central Japan, a region of heavy snowfall. One group of 16 birds was a summer visitor and the other two groupsof about 20 birds were resident. Out of 14 nestswe observed in 1983, six had one to two helpers, one had no helper, and at the other seven we could not confirm whether helpers attended or not. Therefore, 43% to 93% of nests had helpers. One helper was known to attend at least four nests, and seven of 14 marked individuals (50%) acted as helpers.These resultsmean that cooperativebreeding occurs regularly in this population.

We enjoyed great weather for birding, with almost no morning rain throughout the trip, and just a few delightful afternoon and evening showers. Comfortable accommodations, iconic landscapes, abundant, delicious meals, and our charismatic driver Luís enhanced our time in the field. Our group, made up of a mix of first- timers to the tropics and more seasoned tropical birders, got along wonderfully, with some spying their first-ever toucans, motmots, puffbirds, etc. on this trip, and others ticking off regional endemics and hard-to-get species.
