Résumé :	Two breeding records of the Broad-billed Roller Eurystomus glaucurus in The Gambia, in August 1998 (a fledgling being fed by two adults) and August 2019 (a corpse of a recent fledgling), constitute the first proof of breeding in the country. Photographs show that juvenile Broad-billed Rollers are separable from adults in the field by their dull plumage and bill colours, which gradually assume the adult hues but with the underparts passing from their initial brown through a blue-green phase before attaining the adult's lilac. New data for Senegal show that breeding occurs in coastal northern regions on average about a month later than in Casamance.
