Backyard Birding / Coopers hawk, earlier today
« Last post by Napper on December 17, 2024, 05:04:39 PM »Around 1:20 pm today I noticed this Coopers hawk two doors down in a tree. It was there for quite some time.
It was gone after I returned from dropping my kid off at work.

edit
ps Thinkin this a Young Female Coopers Hawk... When I first saw it I Though is that"s a Red Tail. Then saw the tail banding and the white under tail's flaring out in the wind. Notice the yellow eyes....

« Last post by Shortsighted on December 15, 2024, 03:30:17 PM »You have quite logically answered most of your won questions. Quite true, conglomerate can look like weathered concrete, which is really a man-made form of conglomerate. However, concrete is made from cheap, plentiful material that is quarried on Southern Ontario, such as limestone, sand, lime and I doubt that there will be much in the way of igneous, or metamorphic rock found within concrete.
Your sample has either a piece of diorite or syenite, hence it is conglomerate with a sand matrix. I much finer version of sedimentary rock with tiny sharp-edges pieces within a much finer-grained matrix, like silt is called breccia. Since your sample slightly fluoresces under UV light the light & dark speckled rock is probably syenite, instead of diorite, because the former contains fluorescent sodalite. Some of the red-pink colour comes from pseudo-fluorescence coming from potassium feldspar (k-spar), also called orthoclase. The rounded stone with all the poorly fluorescent red is caused by feldpsar. The dark minerals within it are probably hornblende, maybe some biotite mica. It is, essentially, red granite with a lot of k-spar.

In this video, I will show some of the most interesting ones. I struggled to pronounce "conglomerate," but the video has subtitles.

There were seven slick doves on the feeder I say, seven slick doves in a group, if one of the doves should then become prey there would be six slick doves on the feeder I say, should still one more of those slick doves become prey, then there would be five slick doves on the feeder today.
