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 18^th, 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

4th egg

Good Monday afternoon everyone. 

Last Thursday (April 2nd), I received a report that a 4th egg had been laid.  The next step is to estimate when incubation began. 

Peregrines typically start incubation when the next to last egg is laid (the penultimate egg). We're guessing that the third egg was laid on March 31st or really early on April 1st. Since incubation lasts about 33 days, we can expect the first egg to hatch about May 3rd.

That being said, the great thing about keeping up and continuing this blog is the historical reference points.

(Thank You Donna Schwab!!!!)

The last year that we were able to track this pair during nesting season was 2017. As I looked back over the historical posts, I learned that Durand laid her third egg on March 29th, resulting in the first hatch of that season occurring on May 1st. She is pretty much on that same path for this nesting season.

2020 Columbus Peregrine Falcon Update

I am very happy to report that Durand and her partner (30/Z) have returned to last years nest site at the corner of E. State Street and S. 4th Street.

As of yesterday the pair had 3 eggs. Yeah!!!

Triad Architects reached out to inform us that the birds had returned and were nesting.

They have gone to great lengths setting up a camera system that would allow them to share pictures  with ODNR Division of Wildlife so we can share with you what is happening on the ledge.

In this time of social distancing we are very fortunate to have the opportunity to view the happenings of the Columbus and Lima falcons.

In a day or so Durand should lay a fourth egg. Then incubation will begin.

In the 2019 nesting season, this same pair successfully fledged 4 chicks.
