This flower has many different names including Conch flower, Butterfly Pea, Nil Katarolu (නිල් කටරොළු) , Nil Katrol (නිල් කට්රොල්) but the most interesting of them all is without doubt Clitoria ternatea, a name derived from the word Clitoris.
Late last year, a pair of spotted doves built a nest amongst the rafters in our house. They laid eggs on it at least three times. Sadly just after the third pair of eggs were hatched, one of the parents fell victim to a cat. Fortunately the Single Parent family did survive, but after the chicks flew off they never came back, That is until now. This photo is the last time I so them, they were wondering about out of the nest and the next morning, they were gone
I don’t know the life span of a dove, so I would tend to think this is one of the hatch lings, now all grown up that has returned to the nest rather than the surviving bird from the original pair with a new partner.
