More butterflies in March Victoria Mansilla contributed with a great deal of butterflies she photographed during March. I took from all the material those butterflies which had not been published during this month and those, in some cases repetead, showing the ventral and dorsal view which are different. With this third group March ends with a record of 39 butterfly species and two moth species

Diego Bastías tells us he identified a Rufous-browed Peppershrike
Cyclarhis gujanensis from a photo an observer took near the burnt area at Viamonte. This bird was last seen in 2009. A photo and voice of the Rufous-browed Peppershrike for those who do not know or remember it

Matías Juhant says this is an immature, most certainly in its second year. The photo is not good enough to appreciate the colouration of the feathers. But secondaries are shorter. The tail has a conspicuous subterminal band which is characteristic of a second year.

Este es el adulto y pertenece a la familia Castniidae. This moth has diurnal habits. The larvae are very harmful to the palms they feed on. They bores gallerie in the trunk and stems causing great damage. Different palm genera are taken as hosts.
Big Lazy
Actinote pyrrha
Perezosa grande/Big Lazy© J. Simón Tagtachian This big lazy shares the Baccharis sp with two flies of the family Syrphidae. This family is characterized by emulating wasps and bees. The yellow band on the thorax reminds of the camuati wasp which is very common in the reserve. The flies belong to the genus Palpada. CR

I could not corroborate what had happened to the eggs, I only observed that there was one adult flying over the nest site. Only when i enlarged the photo did I see at least three had been born. The nest with four eggs detected by Amelia was successful.

Striped eyes, bee-like body, but it is a fly. Flies which belong into the family Syrphidae, as this case, are characterized by emulating wasps and bees. This provides protection against their predators. They emulate these hymenoptera so well that they can be seen hovering. When adult these flies feed on flowers.

It sang endlessly. It was worth waiting for it. It showed up at the edge of the vegetation and Carlos spotted it when it moved. Among cattails in the shadow and quite far from our position this was the best he managed to obtain.There were two crakes. One seemed a juvenile due to the brownish colouring of the bill.

Here we can see how peculiar the foot of this female green kingfisher is. Like the majority of birds it has three forward-pointing toes and a back-pointing one. But the three toes are not separated. The two external ones are fused at the base and then separate. It is called syndactyl foot and is typical of this family, the Alcidinidae.
