Is 65* and overcast with no rain too much to ask for.....?????
Subtract 20-30 degrees from that to get them on their feet to feed. Warm weather is your mortal enemy. You can always put on more/different clothing to stay warm, but, warm weather will have Moose lazing the day away somewhere you can't see/find them. 65 degrees humping bogs in knee-boots/hippers and rain gear will make you miserably sweaty and hot. 35-45 degrees and you'll be able to pace yourself for warmth and not get soaked from the inside-out by your own sweat.
