The Great Blue Herons have been building their nests for the last week and a half. This nesting location is in Norman, OK. It's on Franklin Rd (looking south) between 12th and 24th Ave NE. The nesting site follows a creek...prime nesting area.
The males gather the sticks and bring them to the waiting females. The females build the nests, after the larger sticks are in place and the basic nest is built, it is lined with smaller sticks, dried grasses and other soft materials. It's amazing to watch this event. Some of the reasons this is perfect nesting site... the creek, farmland, and open fields. They have an abundant supply of fish, reptiles, small mammals, insects, and other yummy treats.
You might be able to see a heron sitting on a nest in this photo.
Each nest has a female or male on it, the eggs have been laid. Both the males and female take turns sitting on the eggs. The female are on the nest during the night and during the day as well.. Once laid, the eggs (2-6) will be incubated around 30 days. The eggs are pale blue when laid and fade a bit as time passes.
The Great Blue Herons have 1 to 2 broods per year. This nesting site is noticeably smaller this year. There is less the a dozen nest so far, I'm not sure why? There could be a half a dozen reasons. I'm just excited they are still using this nesting site.
