Eagle Parenting Mistakes

There's an interesting clip of the Decorah Bald Eagle nest live cam.  You get to see a minor parenting mistake made by the male eagle.  The female ends up fixing it, but night right away.  One thing that I find fascinating about the cam--well all the prey items, Monday one of the birds brought in a muskrat.  But you can also see that it takes the pair of eagles awhile to figure out how to solve the problem.  That hamster wheel in their brain doesn't turn very fast. The clip is about six minutes long, but I'll show you some high lights with screen captures:

The male was noodling around in the nest.  He didn't appear to be feeding the chicks, but picking out uneaten food morsels. The newly hatched chicks instinctively go to peck and beg when the adult's head comes down.  This poor eaglet bit into the male eagle's face, looks like right below the eye.

The male jerks his head back and flicks the chick off.

The male then kind of stares at the moved chick for a bit.  I think he realized that the chick is not supposed to be there, but doesn't know how to move it back.  The chick, out on the edge of the nest where it's cooler begins peeping.

Since the chick is peeping and the male doesn't know what else to do, he feeds it.

Then he hunkers down and broods the chick and remaining egg in the nest cup (I don't think that third egg is going to hatch). The moved chick looks rather indignant.  The chick is too small to do much movement on its own and it's still fairly cool, if this chick doesn't get moved back to the middle of the nest to be brooded by the adults, it could die of hypothermia.

The female returned and kind of pushed the male off, who made a hasty retreat. Perhaps he didn't want to be around when the female realized one of the chicks had been moved?

The female soon hunkered down on the chick and egg in the nest cup and it took her a bit to suddenly notice the eaglet outside of it.  Even then, you could see her trying to work out in her head what was wrong and how to fix this.

It took 2 or 3 attempts for her to move the chick.  She has to be careful, her beak is meant to rip open animals for food, so she doesn't want to accidentally injure the chick.  During the final attempt she was able to kind of roll the chick under her.  So, a happy ending...but it did take a long time.  One of the reasons eagles lay 2 or 3 eggs is that the goal is to get one of those to result in a young eagle leaving the nest.  There's the first egg and the others laid after that are a back up plan--insurance in case something happens to the first hatched chick.  So many things can go wrong from not enough food, rough weather and well, parenting mistakes.

Also, something else I noticed in that clip is the bird watchers:

See the 2 vehicles?  You can even see someone behind the vehicle on the right.  Do they know this is the live cam nest or are they random bird watchers?

Here's the YouTube video if you would like to watch the eagle parenting mistake:

Birdchick Podcast #20: Pranks, Pelicans & Penguins

Non Birding Bill and I are going to experiment with a longer podcast this week.  We are opening a show that is a paroday of The Love Boat at the Bryant Lake Bowl this week and chances are good we will not be able to keep up with doing three shows this week.  Let us know if you would like this to be shorter and more often or once a week and longer. You can follow me on Twitter @Birdchick (ask me bird questions) and you can follow NBB @bstiteler (do NOT ask him bird questions).  You can always email me sharon at birdchick dot com or connect with me via Facebook here.

Speaking of Swarovski Optik, have you seen Pete Dunne's review of their new 10x50 and 12x50 ELs.  He loves 'em!

Bird Blogs:

In today's podcast, we talk about some of my favorite online birding pranks for April 1, 2011 as well as one of my all time favorite bird pranks--that still gets traffic today.

This year's top pranks:

I think Non Birding Bill will love this: Discount Bird Calls

American Birding Association Checklist Changes

Earth, Wind and Water Blog announces plans for ESPN8 to host American Birding Big Day tv show (I totally fell for this one)

Win a Free birding trip to Thailand with David Sibley and ABA President Jeff Gordon at 10,000 Birds

A prank I aided in pulling with another blogger who wishes to remain anonymous (but if you buy me a single malt scotch at a Birds and Beers, I'll gladly verbally out this person) about the "rediscovery" of a Carolina Parakeet.

Bird News:

This unfortunately is  not a prank.  An Arkansas Delta flight hit a flock of birds.  They were not identifiable according to the news article, but I think many birders can see from the photos (WARNING GRAPHIC) that they are American white pelicans based on the upper bill, yellow skin in front of the bill and black wing tips.

We mentioned the oil spill threatening rockhopper penguins on an island chain located halfway between Africa and Argentina in the podcast a couple of weeks ago and in more hopeful news, there are at least 5000 penguins that have been gathered for rescue. The death toll so far appears to be 300 penguins but it sounds like state officials and local volunteers are working as hard as they can to help this breeding colony.  Here's a great video of one of the first people on the scene...it's sad to note that the penguins are not the only ones affected by the spill.  If you want to help, send money to International Bird Rescue Research Center.

Dacorah Live Bald Eagle Cam gets so much traffic with chick hatching that it crashes the siteHere are highlights of the hatching.  Early on  you can see the beaks "pipping" out of the eggs and by the end there's a floofy eaglet.  You can try and watch the live cam here...if it's not too overloaded with traffic.  It is nice to have on as background to your work day--it's excellent video quality and the sounds of surrounding birds is awesome.  Here's a screen shot from Sunday night and you can see quite the buffet: rabbit feet, crow and a fish:

Black Ducks Wear Dog Masks Too!

The Mississippi River has been flooding a bit in downtown St. Paul, MN.  It's an exciting time for us park rangers at Mississippi National River and Recreation Area.  I've been out taking photos for the park's Facebook Page of the progessing river levels and can't help but get in some spring birding when I'm out and about.  See the tangle of trees on the right behind the rail?  There were a pair of song sparrows lurking in there.

There was no singing on territory but anxious chips from the pair.  I think they were looking for food and I wondered if they had nested in this spot last year when the river was lower.  Now they arrived and were perplexed at the dramatic change in water level.  Normally, the river is about 9 feet and when I digiscoped the above image it was over 18 feet.  Soon the river will recede and the birds can go along with their nesting plans.

There's plenty around for the song sparrows to eat.  I saw this early spring insect near the trees (that white stuff in the back of the photo is unmelted snow--yes, we still have some).  There were bird feeders nearby by too, chock full of millet so the song sparrows should be fine.

Ducks have been enjoying the high water, foraging in the grass right off the river.  Above you can see 2 mallards and an American black duck.  Remember the whole meme of Ducks Wear Dog Masks?

Apparently black ducks have do too, it's not just mallards.  Their dog mask is a bit more subdued.
