The past three years, we have celebrated Father's The past three years, we have celebrated Father's Day with this silly little photoshop of Grinnell. Father's day typically has fallen at a time in the breeding season where everything was winding down a little bit, the chicks were all flying and learning to hunt on their own, and Grinnell was perhaps getting a bit of well-deserved rest (and a cup of coffee?).

This year has been a season like no other. On March 31st, we thought there was almost no chance that we would have a successful breeding season. But then we all got to experience one of those rare alignments of circumstance that salvaged some positivity from an otherwise tragic event.

Annie did not spend the night Grinnell died alone, as many of us expected. Instead, perched on the balcony all night was a little male falcon, who ended up being named Alden. Annie almost immediately accepted Alden's courtship and he quickly began to help at the nest site: bringing food for Annie and incubating the eggs. Just two days later, we were surprised again to see that Annie laid a third egg, indicating even further her acceptance of a new mate.

Alden has been an exemplary father to these chicks. He has cared for them, fed them, protected them from intruders, and cared for Annie. Yesterday, the day before Father's Day, and 80 days since Grinnell died, both chicks flew for the first time.

So today, we celebrate Alden and Grinnell, the two falcon dads who made this breeding season possible! Happy Father's Day, Alden and Grinnell! We hope you're grilling up some nice pigeon wings for the family today, Alden.

Alrighty, so that was fast... Grinnell Jr. hopped Alrighty, so that was fast... Grinnell Jr. hopped out the window, immediately flew in a quick loop and landed back on the nest level. He then flew again a minute later and is now in a tree. Both chicks have passed the first major test and had successful first flights!

As we wait for our chicks to make their first flig As we wait for our chicks to make their first flights, we have some exciting pictures of Lawrencium’s 2022 brood (Annie and Grinnell’s grand-chicks). They had two chicks this year on @alcatraznationalpark and biologists report the family is doing great!
