We have your nestflix! In Decorah, DH2 explores self-feeding and shows us its tiny popping pinfeathers, HD makes a difficult fish delivery, and HM starts a rousing game of limbo with the very wonky stick. DH2 is getting big and it’s time to raise the crib rails! At Decorah North, we see some really interesting grackle behavior. Even if you don’t watch the whole video, I absolutely recommend checking out the song spread – it made me think of courting
As DH2 starts to sprout pinfeathers, we’re getting questions about natal down, thermal down, and juvenile feathers. Unless otherwise stated, the information in this blog applies to altricial birds, although most research in this area has been done on precocial and semi-precocial birds like ducks, geese, and cranes. Altricial and precocial birds have some marked differences in pre-hatch follicular development and post-hatch molts. Natal down, thermal down, and juvenile feathers Does thermal down sprout from natal down pores? Do flight
We’re writing a series of blogs about the first few weeks of an eaglet’s life. An eaglet spends roughly 75 to 80 days in the nest. For about the first half, it grows and gains weight. For about the second half, it grows flight feathers and starts developing the skills it will need post-fledge. We will focus on week four in this blog. During week three (fourteen to twenty-one days), DH2 shed most of its natal down, gained a lot
We’re sorry to let everyone know that six didn’t make it. In reviewing the footage, it appears the gosling hit a branch on the way down and suffered a severe spinal injury. We can remove logs and dead wood from the bottom of the tree, but we can’t do much about large living limbs and we aren’t going to discourage nesting in N2B. Five out of six goslings survived the jump. This translates to a survival rate of 83%, which
The goslings jumped this morning at about 7:29 AM. After watching them yesterday afternoon, we thought the jump might occur pretty early today, but we were still surprised at how quickly it happened! Within just a few minutes of MG’s departure, all of the goslings had joined their parents on the ground. Our camera operators were only able to find five of them, so we headed into the underbrush to find #6 hidden under a log. We tried reuniting little

What are we looking forward to this week? Hatch has started at the Canada Goose nest, which means the leap of faith should happen tomorrow or Wednesday! The Missouri Turkey Vultures laid their first egg in the loft early on Sunday morning, so we’re looking for a second egg later today or very early tomorrow morning. DH2 entered its third week of life on Friday, so we’re watching for grey thermal down, emerging ‘mohawks’, and possibly pellet casting. It appears
Is that a pip? A sharp-eyed volunteer alerted us to what looked like pips in a few of the goose eggs this morning. It could be dirt, but we’re waiting for hatch and the marks are on the right side of the egg. We’ll keep watching!
Gosling hatch is right around the corner (April 22nd) and we’re getting a lot of questions about the gosling Leap of Faith. Will the goslings jump? How will they survive? Are they really ready to leave the nest? Read on for the answers to your questions! Will the goslings really jump? They will! Watch for The Leap of Faith to happen roughly 24 to 48 hours after hatch. Mother Goose will leave the nest and both parents will start vocalizing.
