Limited success with the bee hotel. 19 red mason cocoons and signs of interest from a leaf cutter bee
A tray from a 'bee hotel' with four grooves, two are 8mm wide and the others 10mm. One of the wider grooves is empty and the other is partially lined with pieces of dried leaf. The other two grooves are sealed at one end, lined with mud and contain 9 and 10 cocoons, respectively.

On the beach
Photo showing a view the sky over a beach with low dark cliffs on the left. The sky is progressively lighter from left to right of the photo with dull grey clouds on the left merging into small white clouds in a blue sky on the right. There is a bright, double rainbow arcing from the horizon on the lower left to the top right of the photo.
