Abstract: Female Vervain Hummingbirds (Mellisuga minima) and a Jamaican Mango (Anthracothorax mango) were observed to ingest calcareous grit or dust in Portland Parish, Jamaica. The clustering of observations during the last week of March suggests that calcium-rich grit was ingested to facilitate egg shell production.
