@joelsegovia Thank you to you and @dropahead! The trick is to find their cleverly hidden nests. Then to keep track of the movements at the nest and once feeding starts then I know that there is babies in the nest. Of course all of this takes place unobtrusively. We have made our garden bird friendly by planting Pincushion bushes and we have a very large Granadilla bush next to the house that offers them safety from predators. I count the weeks once they start to feed at the nest and then I try to be ready more or less for the appearance of the babies. Of course if they sense my presence or any other danger, they will simply abandon the nest! Distance and patience is required! Thank you once again! Blessings!
