During my visit I saw a Scrub Blackbird which seemed to be eating yellow flag. He did it very delicately since it put it head into the flower and then out of it. A while after the blackbird had left the yellow flag, a Golden-billed Saltator stood on the same plant and, unlike the blackbird, the saltator began to tear it apart conscientiously so that no petal was left

This swallow is a boreal migrant. It comes to the south to spend summer and goes back to the Northern Hemisphere to breed.
It looks like the brown-chested martin but it is smaller. Its tail is relatively short and barely forked, tail undercoverts are long and the collar is very wide laterally. It does not vocalize while on flight. This individual was flying among white-rumped swallows Tachycineta leucorrhoa and brown-chested martins Progne tapera. They were rather high and far.

The caracara was walking very unconcernedly. All of a sudden he stopped and leapt ot one side to catcha a prey, or it was there beforehand. I do not know. It seems to be a pigeon. Feathers kept flying ceaselessly

Eating loquats
A plant which though it is exotic is frequently visited by birds and insects. So it is a must to stop and wait both when it is in bloom or with fruit.
