Let’s Try Some ‘Deductive Reasoning’

Observing the photo at the bottom of this page, courtesy of young Hellen Hidalgo, we see a sizable tree near Campo Dos y Media in the southern zone of Costa Rica.  In this tree we can also see about 14 or 15 spectacular long pendulous nests built and maintained by Crested Oropendolas (shown here, courtesy of Monique Girard):

As we observe the photo below more closely we notice a few interesting features of these Oropendola nests.   Let’s put on our Deductive Reasoning Caps and ask ourselves, ‘Why?’.

  1. Why are the nests constructed very high up in an isolated tree?
  2. Why do the nests seem to be hanging from the extreme distal (furthest from the tree) part of the branches?
  3. Why do the nests all seem to be on just one side of the tree?
  4. And lastly, why are the nests communal?

Over countless generations, Crested Oropendolas have found this particular lifestyle to be the most successful for them; the best way ensure that their genes are passed on to another generation.  All organisms do the same; we call this Population Dynamics or Population Ecology.

FYI: These questions are merely rhetorical and posed just for fun.  No homemade cookies for the best answers.

POW: Photos of the Week for July 7/Fotos de la semana: 7 de julio

Our two birds for this POW were taken in the small town of Caracol, near Rio Claro.  The great husband and wife team of Yeimiri Badilla and Marilin Saldana brought us these amazing photos.

Photo #1: You should recognize this bird from all of our San Vito Bird Club publications, t-shirts and coffee mugs; it is the Turquoise Cotinga!  Taken in their front yard.

Photo #2: Taken in the palm plantations near Caracol.  Palm oil plantations often contain a surprising variety of bird species.  This young Striped Owl was probably in search of small rodents who feed on the palm nuts.

POW for June 19: Parakeet and Woodpecker!

Normally, our two Photos of the Week (POW) are somehow connected.  (See last week…both birds have streaked breasts.)  This week I’m challenged to find a clever connection between these two birds; Olivaceous Piculet and Sulpher-winged Parakeet.  Sure, they both have feathers, a cloaca and lay eggs but I’m looking for a CLEVER connection!  Your help appreciated.

The Streakers! POW for June 2018

Our first streaky Photo of the Week comes from Finca Cantaros duena Gail Hewson-Hull.  This streaky-breasted bird is a Sulpher-bellied Flycatcher.  One of our larger tyrant flycatchers, the Sulpher-bellied is more often seen feeding on fruits than catching flies.

Our second streaker comes from SVBC President Emeritus Alison Wickwire-Olivieri.  Many birders who come down to the southern zone have this bird, the Streaked Saltator, on their must-see list.  FYI: that bill is heavy and powerful!  Distinctive and musical song.

Kids Learning to Use Binoculars!

Few things inspire greater optimism for a healthy future than observing excited school kids learn how to use binoculars (see below).

The San Vito Bird Club along with our Detectives de Aves (Bird Sleuth) crew of educators are asking for your financial support.

As our education programs expand across the southern zone of Costa Rica we need more binoculars for the kids to use during their Detectives de Aves lessons; two lessons in particular.  One lesson is dedicated to proper use of binoculars in the field and the last (and most popular) lesson with binoculars is a half-day field trip into a rain forest full of birds!
