Some of my photographs have been used for various publications. Others have been winners in local bird photo contests. One photo was used in 2007 as a theme photo for the KAAY FECC - Festival international de toutes les danses, 4ème édition du Festival Kaay Fecc, held in the République du Sénégal.

In 2007 I published two books using the Blurb book website. One book, called Aves del Parque Central de San Juan, can be seen here: http://www.blurb.com/bookstore/detail/54071. The other is a nature photo book of the Caribbean Island of Dominica. It can be seen here: http://www.blurb.com/bookstore/detail/51132. Also many of my bird photos can also be seen on two other excellent sites: http://alfredo.colon.oiseaux.net/ and http://www.oiseaux-birds.com/home-page.html. The endemic species can be seen here: http://www.oiseaux-birds.com/article-island-birds-endemic-puerto-rico.html.

I’m a contributor to the Encyclopedia of Life in the internet with Dragonfly (Odonata) photos, http://www.eol.org/, and to the local Ornithological Society, Sociedad Ornitológica Puertorriqueña, Inc, https://www.sopipr.org, with local bird photos. I'm also a contributor to the Center for Biological Diversity, http://www.biologicaldiversity.org/, which used one of my photos for a special conservation petition before the Secretary of the Interior of the United States:

In a recent issue of the scientific journal LIfe: The Excitement of Biology 3(1), there is an article by Javier E. Mercado and Jorge A. Santiago-Blay, called Multiple Model Mimicry and Feeding Behavior of the Spider Web-Inhabiting Damsel Bug, Arachnocoris berytoides Uhler (Hemiptera: Nabidae), from Puerto Rico, in which one of my photos was used.  You can read the article in this link:
