| Event | Monarch PEAK Migration |
| Date of Sighting | 10/12/01 |
| Comments | We're having another "river of monarchs" flow through Eagle Pass today continuously since 9:00 a. m.
I just picked one small strip of visible sky out the window looking northeast and counted everything that crossed it in one minute. There were 93. I just got out the calculator and did the multiplication on that, and it comes to 5580 an hour. And that's just the narrow strip across the width of my yard--
some 150'.
Small breeze quartering out of the SE at 10-12 mph. Temps 93.8F. Scattered
clouds, but hot and sunny.
The front came through yesterday (10/5/01) about 7:30 pm and created a few scattered sprinkles. No monarchs. Temps went to 56.1F, then up to 91 this afternoon. Breezes very light from the north. All day the 6th: no monarchs. Then at sunset they began tumbling down out of the skies from the north and clustering in the same trees they have for the last 22 years that I know about. I don't have a count yet, will wait till about 11 p.m. to check and begin tagging. This makes this fall arrival 6 days earlier than previous years. People around Eagle Pass are reporting butterflies yesterday afternoon at 2 a minute. Trees behind the offices for the Rio Bravo Nature Center had two areas of clustering last night when I counted. One consisted of about 200 individuals and the other area, more spread out, had about 10 clusters. One of these I netted and caught 37 in a single net sweep. Scattered and unclustered I'd estimate another 200 or so for a minimum 800 in a 30 yard area. Reported for Carol Cullar Rio Bravo Nature Center by Mike Quinn, Texas Parks and Wildlife. |
