It was about 5: 40 ish. Chapelle came from the south, went north of the Radisson and circled a time or two and then slipped into the box. She did not land on the ledge of the box but went right in. We saw Princess and Smiley after that, she went to the tower, he came from the north, circled and took off north again.
I took some pictures, but I don't think it was of Chapelle returning, it happened really quickly. I will check the memory card and if there are any, I'll get them to you.
I definitely saw 4 birds. But I can't speak for Sparkster.
