Introduction

Organization:


This site, in general, is organized into galleries and folders.   The galleries are collections of images.  The folders may contain galleries, informational pages and even more folders.   As this site is being launched there are a large number of bird images and very small numbers of other images.   At this point, the organization of everything other than birds is quite simple and self explanatory.


In an attempt to bring order out of the chaos of approximately  1500 bird images incorporated to date in this enterprise, a limited use of scientific taxonomy has been chosen.  The bird images are sorted by order and family. Within each, the species follow the  sequence used in the "Checklist of North and Middle American Birds" put forth by the American Ornithological Society.  It can be found at:

To some visitors, this may at times seem unnecessarily confusing and illogical.   But the root problem lies in a collection of common names amassed over two centuries or so which often had little basis in scientific truth.  Consider for example, two groups of birds called grosbeaks, some of which are Cardinalidae and the others are Fringillidae.  In other words, although both groups bear the name grosbeak, modern evidence has shown that they are not closely related.   The physical similarities that gave rise to sharing the  common name are likely a result of convergent evolution.   So trying to cobble together an organizational system based solely on common names, must be fundamentally flawed and ultimately of little value.



Navigation:


The “Browse” function makes its way through choices of order, family, and then the individual species.   Sub-families are also used, but these are not visible to the viewer. 


Every bird image is tagged with the corresponding order, family, and in some cases, sub-family. The “Search” function supports each of these, as well as the common names.


As other categories of images are added, most notably wild flowers, mammals, insects, and astrophotography, the least burdensome classification system will be adopted for each group.  The driving principle is to make things easy to find without creating large numbers of barely populated galleries.


Viewing Tips:


Once a gallery has been selected and the viewer scrolls down to a particular image, a left click on the selection will cause it to expand a bit and a pair of oppositely pointing arrows will appear near the upper right hand corner.   A left click on this icon will cause further expansion, filling the screen with the image and a black border.  This mode presents the images at their best. 


Navigation through the gallery can now be accomplished using either the keyboard right and left arrow keys or by left clicking the right or left arrow icons that appear if the cursor is moved in the image area. 


Clicking on the arrow in the lower left of the screen starts a slide show.  


You can leave this display mode by either left clicking the X in the upper right corner or tapping the esc key.


The viewing features described above are available when using Firefox as the web browser.  It has recently come to my attention that other browsers may not support all of the features described.
