One Chick Left

Watching the Columbus Peregrine Falcon YouTube site this afternoon.
The youngest chick is still on the ledge, but I suspect it won't be for long.
It's running up and down the ledge flapping it's wings, hopping up and down. This behavior is building flight muscles and courage to leave the ledge.
I anticipate that it will leave the nest ledge tomorrow or the next day.

There was a large development gap between this bird and the "twins" (that's what I was calling the middle 2 birds because they were very close in size and abilities).

Below are pictures from last Thursday of the youngest bird and one of the twins. You can definitely see a big difference.

Here is a picture from today of the youngest practicing its balancing abilities on one of the lights.

Leaving the Ledge

The young are starting to leave the nest ledge. I received a report that the first fledgling took flight last Thursday morning (June 11th).
As of yesterday there were still 2 young at the site.
Below is a link to the facebook page of the 2 remaining birds yesterday.

These are photos that I took last Thursday of the remaining young loafing on the ledge.

2 Weeks Old

The 4 chicks in Columbus are progressing nicely. A lot has changed in just 2 weeks.
Everyone is eating well. You can see that in the below picture. All 4 chicks have full crops.

I had the opportunity to visit the ledge today to look at the chicks.
I received a report that one of the chicks was stuck on its back and could not get turned over. It was stuck similar to a turtle being flipped on its shell. Eventually, one of the adults intervened. We have video of the adult picking up the chick and turning it over.

At this stage there is a big difference in the chicks sizes and abilities. The chicks hatched a different times, so there are developmental differences in the things they do.
2 chicks (the first 2 to hatch) are very mobile, walking around on the ledge. A few times I witnessed one of the older chicks trying to stand upright.

The 2 younger chicks still spend a large amount of their time in the "nest" eating and sleeping a lot. This will change in a few days and they will become as mobile as the other 2. So when one of the younger chicks was stuck on it's back it needed a little help to get righted.

4 Chicks!!!!!

By Monday evening, on May 4th all 4 eggs had hatched!!!!
A BIG thank you to Triad Architects for setting up a live stream on youtube so everyone can enjoy watching the Columbus falcons.

Columbus Peregrine Falcons.

Everything is progressing well. I've seen 6 feedings so far today and I sure there will be at least one more before the evening is over.

Second Chick Hatched!

Sometime during the night a second chick hatched.
We get a look at the 2 chicks as Durand gets up to get the food that Z (the male) has brought into the ledge.

Below is a picture of Durand feeding the chicks.
Both chicks ate well and promptly passed out.
Can't wait to see what tomorrow brings.
(Thanks Melissa for the opportunity to take some cool pics.)

New Arrival!!!

At approximately 4:15 pm today there was a new arrival in the nest ledge!
It will be interesting to see what tomorrow will bring.
Durand settled nicely into incubating after the new arrival hatched.

Incubation Update

Things are going well with incubation.
Regular mate changes are occurring every 2 to 4 hours. 30/Z regularly brings Durand food. 

While we are impatiently waiting for the first egg to hatch, I thought I would review a little history of Durand and 30/Z's longevity with the Columbus nest.
Durand arrive in Columbus around July 18th, 2010. Based on her color band (All black 32/X) we determined that she was the 2009 product of a nest in Hamilton, Ontario Canada.
After 2 failed nesting seasons in 2011 and 2012, Durand and Spark (Blk/red 32/B) produced 1 chick in 2013.
From 2013 to 2016 Columbus had the same nesting pair (Durand and Spark).
2014 produced 3 chicks (Dart (38/D), Blaze (48/Z), and Hoshi (31/Z))
2015 produced 3 chicks (Bolt (N/34), Flash 37/Z) and Storm (46/Z))
2016 produced 4 chicks (No Banding)
2017: Durand and a new male (30/Z) produced 4 chicks (Last nesting season at the Rhodes Tower)
               30/Z is a male from the 2014 Bowling Green nest.
2018: We did not know where or if a nesting occurred
2019: Durand and 30/Z produced 4 chicks
