Today was my third visit in nine days to Spring Green Preserve. While Spring Green always holds the allure of it's unique desert prairie wildflowers, reptiles and amphibians, I have been frequenting this natural area more in recent days in hopes of spotting the male Blue Grosbeak originally reported by Daryl Tessen on May 28, 2013. After two failed half-hearted attempts to locate the Blue Grosbeak earlier this month and another birder reporting the bird yesterday morning, I declared I was going to hold a Texas-style bird stakeout and find the Blue Grosbeak. By "Texas-style" I was referring to how I've seen rare bird chases unfold on numerous occasions in the Lower Rio Grande Valley. One basically goes to a relatively small defined area where a rare bird is reported and patiently waits for the bird to appear.

So early this morning despite predictions of severe weather, I set out for Spring Green Preserve (map) arriving at 0730 prepared to wait for several hours until the bird made an appearance. I located myself in the center southwest corner of the preserve waiting and watching in the rain. I decided to do without the camp chair I brought since sitting in a puddle of rain on a chair seemed like a bad idea. About an hour into my quest, I became restless and decided to walk the west edge of the property in the recently cleared area.
As I was poking around, the rain had subsided, so it seemed a good time to get out my macro lens and photograph the Prairie Smoke and Slender Penstemon I had noticed along the western perimeter. I then spotted a uniquely colored white spiderwort and was moving along to photograph this when I heard the full-sounding warbling finch-like song of the BLUE GROSBEAK that stopped me my tracks!

However today, in just 4 days passing, I noticed the presence of these two species had diminished significantly.
