 When I first read the field notes of Annie Alexander and Louise Kellogg, I was fascinated by the descriptions they wrote about the places they went and the plants and animals they found there. By publishing my field notes on the Internet I hope to follow a little bit in their tradition.

Chapel of Bones

Built in the first half of the 17th century, as an extension of the Chapter House of the convent of São Francisco, the Chapel of the Bones is an invitation to reflect on the transitory nature of the human condition, summarised in the words above its entrance:

WE BONES HERE, FOR YOURS AWAIT.
The decoration of the ceiling, dating from 1810 and full of symbols, allegories and quotations from the Holy Scriptures, adds the affirmation of another Life in the splendor of the glory of God.
At the back of the chapel is the 18th-century tomb chest of the founders of the Convent (13th century) and the floor tomb of Bishop Jacinto Carlos da Silveira, who died during the invasion of Évora by French troops, on 29 July 1808.

Pivotal results. Linaria and Nuttallanthus constituted a monophyletic group within the Antirrhineae. Linaria was recovered as a paraphyletic group with Nuttallanthus nested within it. Six major clades were recognized within the Linaria-Nuttallanthus clade. The seed wing, a structure that has been extensively used in systematic treatments, appears to be a homoplasious character in Linaria (Fernandez-Mazuecos, et al., 2013)

Wednesday, 29 July 2020

I was down on my hands and knees collecting Physalis longifolia at Dakota Ridge, north Golden, Jefferson County, Colorado, when I heard a soft rattlesnake sound. Took me a while but I finally noticed it was coming from this little gray bird that was hopping back and forth between the rocks in the foreground. The "clacking" or "chattering" noise was clearly coming from its bill. There are three more similar birds on the brown rock above and to the right of the bird that was out front. I would assume that the four birds were a family group, and the bird making the clacking noise was intending to distract me. Forced to actually look in a bird book, this bird looks similar to but a little smaller than a Townsends Solitaire and a little bigger than a Gray Vireo. Neither of them are known to make a clacking noise or "imitate" a rattlesnake, at least according to my book (Peterson, 1961).

Posted this to Facebook asking my bird-knowledgeable friends for help. They agreed that the location and the soft rattling/trilling, or rattling chatter strongly suggested the birds were Rock Wrens.

Also got stabbed by an assassin bug. It hurt on a scale of 7 of 10 for about 10 minutes, then went away.
