Jacana - a long-toed rail-like bird.

Image
Adult Jacana and juvenile (right) at the San Diego Zoo. Some birds share parenting.  Often though, it's the female that has the duty of incubating, protecting, and feeding the offspring.  But in the case of the Jacana, the male does the lion's share of the work. The Jacana is a rail-like bird with an interesting adaptation - it has really L O N G toes.  So long, in fact, that it is sometimes called the "Jesus bird" because of its seeming ability to walk on the water.  In truth, it can walk on floating vegetation because of how spread out its toes are, reducing presure/area measures to very low values.   The chicks are even more impressive, as their long toes are disproportionately larger than their bodies.  The juvenile on the right in the above image gives a hint to this.  I didn't actually see any chicks; they must be a comical sight.  You can see a video here . They often get their inhabitants as injured or abandoned and raise them in well...

Having fun in Yelapa.

Image
  Kathryn enjoying Yelapa Falls. We had perhaps the best excursion ever yesterday.  We arrived in Peurto Vallarta in the morning and soo after left on our excursion with Peurto Vallarta Adventures, a tour company with a very nice catameran boat and crew. Our tour included three different destinations, one of which was the little town of Yelpa located about half an hour away by boat.  That was the only way to access the community; there are no cars and any mode of transportation involves either an ATV, motorcycle, or mule.  The rough cobblestone roads reflected this as most of them were only wide enough for an ATV to pass through. The focus of the tour was the waterfalls, perhaps a 15 minute walk from the beach.  They were somewhat impressive, not on the order of anything spectacular, but had a good height with a decent flow of water. There was no way I was going in with my camera gear and boots, but Kathryn was already with her bathing suit and watershoes. ...

A little photo-bombing at the San Diego Zoo.

Image
Me at the Asian Elephant display at the San Diego Zoo.  Notice anything? He's not too hard to see, if you look.  The boy is hiding behind the baby Asian elephant.  At first, I thought he was playing with a toy truck, but closer inspection shows that it's a water bottle he is holding.  I am not sure what he was doing, but his parents were several feet away and distracted by whatever was in the adjacent paddock. Photo bombing, also known as the art of showing up in a photo you have no business being in, is often an unrecognized skill held by those of us who have no or little social awareness.  You know the type, walking about without a clue regarding the environment, stumbling into situations they just shouldn't be in.  Often, those situations involve a photo being taken. I, in my socially awkward stage, have unintentionally popped into gatherings and disrupted the proceedings a few times.  Although I would say that I am beyond such things now, my wife w...

Spotted tanager - so many different tanager species!

Image
Spotted tanager at the San Diego Zoo. I have, until two days ago, ever only seen one species of tanager.  The western tanager, the male, a stunning orange and yellow bird, even came to visit me at home once.  But I was unaware of other tanager species.  And then I went to the San Diego Zoo. The field guide of the Birds of Mexico and Central America shows 22 different species of tanager.  The aviary held four different species of tanager; I managed to photograph two of them.  I included the plate below.  None of the four listed are found in North or Central America. Plaque at one of the aviaries showing different species present.  Notice the 4 tanager species. Honeycreepers used to belong to a different taxonomic group, but have recently been added to the tanagers.  There are two on the info plaque above, three listed in the book I referenced.  I don't currently have access to the internet, but there must be dozens of related species, perhaps ...

San Francisco's Golden Gate Bridge - A fun photo project.

San Francisco's Golden Gate Bridge - A fun photo project. When visiting San Francisco, especially by boat, you have to see the Golden Gate Bridge.  I mean that in both the literal sense, in that you pass directly under it on your way into the harbour, and in the figurative sense, in that it is such an icon that it's just one of the things that has to be done. I decided to do a series on the famous architecture; I made a point of photographing it from many points of view.  The time and transportation limited us to exploring it visually from only a few angles, but it was still enough to come away with satisfying results.  We walked for 4 or 5 kilometers, maybe more, from the south entrance of the bridge to the marina to the east.  I originally wanted to explore the southwestern section, but it was fenced off and inaccessible. The area was busy, with plenty of cars, pedestrians, and people on all types of personal transportation devices.  Along the way, we crossed ...

California sea lions at Pier 39 - Horizontal vs Vertical formats.

Image
California sea lion having a good scratch, Pier 39, San Francisco. While visiting Pier 39 yesterday (September 30), we saw the sea lion basking area that is so famous.  Sure enough, there were California sea lions, although not the horde that there is room for.  And their larger kin, the Steller's sea lions, weren't in attendance. I got off a few good shots, but I especially liked this one giving itself a good scratch with its front flipper.  I decided to crop it both vertically and horizontally, making two different files, to compare which one was more appealing and why. I prefer the vertical format, but why?  What makes it better than the horizontal format? After all, they are both the same image.  It turns out it has to do with composition. The two main points, the face and the flipper, are relatively close together.  The narrow vertical format allows them to be near to the thirds positioning.  Horizontally, they are similar, except that there is li...

Snowy egret - telling them apart from cattle egrets.

Image
Snowy egret photographed in San Francisco Yesterday (September 30), Kathryn and I went to the south side of the Golden Gate Bridge.  We walked from there for a couple of hours and ended up at a freshwater estuary called Crissy Marsh. While there, we saw quite a few birds, a great egret, a couple of snowy egrets, and a pair of remarkable curlews.  I will talk about those another day.  I watched the snowy egrets for quite a while and photographed them in various poses. Snowy egrets are "common and widespread."  I have seen them in Texas, in the Caribbean, and of course in San Francisco.  They are easy to identify in that they are mostly white with a distinctive yellow patch around the eyes leading to the beak and black and yellow legs.  Cattle egrets look similar but have a yellow bill and black legs. I have included a photo below of a cattle egret.  You can see the yellow bill and black legs that clearly distinguish it from the snowy egret's.  Catt...
