THE FAMOUS Peregrine Falcons nest on the Joseph Smith Memorial Building has seen no activity since 2015. We will update if a new pair nests in the box.
April 15 @ 12:47 p.m. - I just poppped into the office and watched an adult (I believe the male/tiercel) coming over the front board heading for the scrape and, for the briefest of moments before he reached the scrape, I saw 2 (two) eggs for the first time
Hi Bob! You are commenting on my blog postings?? That's awesome, glad to have you do that. I need help answering questions from time to time. I did the screen capture using Microsoft Clip tool Saturday after noon from my home computer.
I just saw the female fly into the box with a large rat! Then the male flew in and took it away from her and fly away. I guess he was more hungry than she was.
Liz, how exactly do you tell who is male and who is female besides their size? When I see them alone in the nest box they look exactly the same to me. Felicia
Cere, bill, eye-lining and feet: male (tiercel) is orange-yellow in color, female (falcon) is sunshine, or pale yellow in color ... this means that there is a higher contrast in color for the male (comparing cere, bill, eye-lining and feet to slate grey back and cream-colored underparts) Back: male appears "blacker", female, particularly in the area of the lower back, appears scaly/"scalier" (likely due to lighter, or "buffier" feather edges) Tail (tip): male appears dark, female appears to be buffy-colored RW
Size: If you are so lucky as to "catch" an adult perched on the front board (chest facing the east) w/ tail held, or laying over the rock, the tip of the male's tail is close to even w/ the interior (west) edge of the rock, while the tip of the female's tail protrudes a couple of inches beyond the edge of the rock ... I'll continue to look for other helpful tips and welcome corrections & input of others RW
