Chavez Park Wildlife Videos

Videos included in this website from March 2015 to date (with some delays) are listed in this table. The list includes all wildlife videos — Birds, Fish, Herps, Insects, Mammals — and selected others (Astronomy, Issues, Management, Weather). For plants, see the Plants table.

The links (“View”) go directly to YouTube. For commentary about a video, search for the post on this website where that video is embedded, which will be the date of publication given in the table. Or optionally look for the name of the bird in the separate Birds table, or search for the topic in the Categories drop-down on the home page, right side.

Click on the blue column headers to sort the list as you like, forward or backward. For example, click on “Category” to sort by category, click on “Subject” to sort by specific animals, or click on “Time” to find the longest or shortest videos. Enter a term in the Search box to filter the list; for example, enter “Feature” or “Slow Motion” or “Burrowing Owl.”
