During the week last week the backyard bluebirds really started working hard on building their nest. They had been house shopping for quite a while before they finally decided. Their indecisiveness was a blessing in disguise due to the fact that if they had picked a week earlier they might have been in trouble. We had very warm temperatures followed by a week of mostly freezing temps. If they had moved in and laid eggs a week earlier they might have lost the eggs due to the cold. Luckily for all, they are picky.
I spend a lot of time watching these birds. Easily double the time I spend photographing them, possibly more. I've been noticing during nest building that dad never really brings in any nesting material. It appears that mom is doing all the hard work. So I spent some time watching dad to see what his whole role was during this process. Dad's first role was to be a watchbird. He was always at, or near, the house watching for invading birds. He sat on this one tree stump that is about 10 feet away from the house constantly watching and attacking anything that came near the house. Mostly running off House Sparrows and other birds that were brave enough to investigate the situation.
Another role dad played was making sure mom didn't burn off too many calories during all of her nest building activities. Many times mom would go to the ground in search of the perfect piece of straw and dad would follow her with a mouth full of mealworms. He would then offer her the mealworms. He did this over and over. On the ground, at the tree stump and on top of the birdhouse.
Although dad didn't "look" busy and it looked like mom was doing all the hard work, dad was doing his part, too. Heck, he might even do the dishes later.
These images were made with my Nikon D500 and Tamron SP 150-600mm Di VC USD G2 Lens. The camera was mounted on my Sirui Tripod and PH-20 Gimbal Head.
