Honey production in Uruguay occurs mainly during spring and summer. However, on the East coast beekeepers can extend their production into autumn and winter. To analyze this situation we chose an apiary located at the mentioned area where population parameters were recorded during a year. Nectar and pollen loads samples were also analyzed to determine their botanical origin. Over the sampling period, the colonies had high population sizes. Eucalyptus spp. pollen was dominant in most nectar and pollen samples. Other relevant species were Baccharis spp.Trifolium repens, Acacia longifolia, Lotus sp. y Eryngium spp.
