More juveniles
Two other juveniles
I take these two photos of dragonflies by Claudia and Tito to tell you that this Saturday (26) along Viamonte Canal to the coast there was a strikingly odd number of dragonflies flying low. Dragonflies feed on mosquitoes and other small insects. They must have eaten them all because mosquitoes were conspicuous by their absence.

Going on with the youthful line
Rufous-collared Sparrow
Zonotrichia capensis

Juan Klavins provided this valuable piece of information: "It must have been born 4-5 weeks before the photo's date. This plumage lasts a short time. It soon changes into the first basic plumage (preformative), which resembles the one before the breeding period both in one- or two-year olds".
Masked Yellowthroat
Geothlypis aequinoctialis

This juvenile was very quiet. We found it on the grass. It moved into the vegetation, found a butterfly and ate it. It went back into the grasses, found a cricket and ate it too. And a third time in he went and was no longer seen
