Death by micro plastics, M2 is here…Monday in Bird World

8 May 2023

Good Morning Everyone,

Sunday was an overcast day with the feeling that rain could start anytime. It didn’t. The garden feeders were busy! Unfortunately, the squirrels have figured out two different ways to get on the table feeder, causing issues with the birds. Still, they waited and watched. Mr Crow is also afraid of the feral cat that visits and, as a result, has not been quick enough to feed well today. Silly boy. Today they also marked the first day for the White-throated Sparrows to be in the garden this season. In a few days, there could be fifty or sixty of them. If all goes to plan after they arrive, the Orioles will eat oranges and Grape Jelly and pay no mind to Dyson and her gang.

So proud of itself!

Mr Blue Jay watched and waited til he could get a turn at the feeding table.

Your smile for the day…

So far it has been a good Sunday at the nest of Angel and the Baby. This was the posting of the prey delivery and feeding. It is windy and the weather could turn stormy. As I am writing this there has been a feeding at 12:53 with a partial piece of rabbit that Tom delivered. A second feeding began at 2:07:40. ‘A’ has sent me the entire time stamps for the action at the nest. Here they are: “Time stamps for today (7 May) at Angel’s nest. Spoiler alert: Tom brought in some food around lunchtime, which was enough to feed the hawklet three times. Okay, time stamps: 07 02 45 Angel up, wing stretch,head scratch,BJS buzzing her. 08 32 31 Angel up and spots something. And the BJs spot her. 08 39 44 She leaves. 08 41 01 She returns. 10 05 59 After a big wing stretch Angel leaves.10 15 42 PTZ camera Angel flies by on her way back to the nest. 11 46 25 Angel aerating the nest and some preening. 12 52 15 Tom in with part rabbit?. 12 53 30 PTZ feed starts. Some leftovers for later. 2:06:50 RTH5 falls over, gets up after a struggle. 2 07 40 PTZ Second feed starts. 12 51 Angel up.big wing and leg stretch and preening. RTH5 Preening itself. 3 22 00 PTZ Start of third feed. 3 41 44 Angel swallows a lump of fur/skin. 6 06 55 One For the PS fans. This chick is the most adorable little thing ever. The way Angel looks down at it with sheer unadulterated adoration is just precious. I love this chick way too much!”

Thank goodness for small miracles. Angel sure can use them. Let us hope that the storms and potential winds and tornadoes do not hit this nest. This couple needs to find prey and keep it coming so that the baby can develop properly. It sure looks like a hardy little one.

There is something magical about the way that Red-tail Hawks look at their chicks. Big Red is the same. You simply melt at the love in those eyes.

Arlene Beech caught the prey delivery for us.

The weather turned with heavy rain and thunderstorms. Angel is keeping her baby snug and dry.

The situation is also good at Achieva where Jack brought in two fish almost at once. Big Bob ate its own fish while Mum fed Middle. Smiling. Both osplets are safe and find and it is probably that the Bald Eagle wanted the fish and not the osplet! If it had been younger, yes.

Barbara Snyder reports on FB that Mum brought in one of her big catfish and Dad brought in another fish – so another double delivery – Sunday evening that is keeping this nest happy. This is wonderful news for Achieva. These two have their juvenile feathers and well, we don’t want to lose either one of them!

Sadly, the first delivery at Lake Murray did not come until late in the afternoon. Kathryn observed that Mum went out to possibly find fish several times but returned empty handed. Little Peanut did not get any food and this osplet does not look well to me. As Kathryn notes it is also not being clever. I think we should brace ourselves for a sad ending for this very tiny third hatch.

No food for Peanut this morning. It is so very slow and sad to see a sweet baby die of starvation. Only a miracle will help this wee one.

I will add a few articles, once in a while, or postings that discuss siblicide so that we educate ourselves. In 2012, Dr Erick Greene, the Professor at the University of Montana associated with the Osprey Research Project and Iris’s Nest, wrote this post for Montana Ospreys FB Group. It focuses on the amount of food brought to the nest. Other research studies suggest that the oldest or most dominant (usually the same) are getting the majority of food, so siblicide makes no sense. Hopefully, you will enjoy and learn from the articles coming up, and they will provide much to think about as you watch the nests that are getting ready for osprey hatches.

Siblicide – part IV

Siblicide occurs in MANY species of birds and other animals, including all hawks and owls, egrets and herons, kingfishers, pelicans, boobies, cranes and some others. Although it may seem cruel, it is an adaptation that allows the parents to raise the maximum number of healthy and vigorous young under fluctuating and unpredictable food supplies. When there is enough food to go around, all the chicks thrive; when food is limited, only the number of chicks that can be supported survive. So siblicide is a self-adjusting mechanism that matches the number of chicks with the available food.

This is what siblicide is and why it occurs. It is a completely natural part of Osprey biology (and the biology of many other species). However, this does not mean it is easy to watch – it is quite disturbing to watch a chick kill its sibling. Last year fishing was so tough that about 95% of the Osprey chicks starved to death around Missoula. While we were saddened and disturbed to watch the two chicks in the Hellgate nest die last year, we rejoiced that Iris and her old mate were able to raise one very robust and healthy chick in such difficult circumstances. This is something not many Osprey pairs were able to do. If there was not siblicide, all three chicks would have starved to death last year. Nature can be “red in tooth and claw,” even within a family. Even though siblicide may seem cruel to you, there is some sort of comfort in a system that allows the Osprey parents to raise healthy chicks even when times are tough. This is part of the reason we still have thriving Osprey populations.

Some of you may wonder why we don’t take the smallest chick from this nest and put it in the Dunrovin nest. We are not allowed to interfere with this natural part of the Osprey cycle. Our research permits and animal care permits (that are very strictly regulated) would not allow us to do this.

We are giving you this information to let you know about a natural and expected part of Osprey biology, and prepare you in case the smallest chick does not make it. So what can we expect at the Hellgate nest this year? The third chick is definitely running from the back of the pack, but the new male is a fantastic provider! I just watched carefully and saw the smallest chick get absolutely stuffed with part of the large trout the male brought in (Tuesday, 26 June 2012 about 1115). This is a good sign, and if the male continues to be such a good provider all three chicks may make it! Think pure thoughts.

That was 2012 and much has been learned since then. I hope to enlighten us more in the coming weeks.

Oh, I wish I could wiggle my nose and transport Peanut to the Moorings Park Osprey platform after Abby and Victor fledge…those two are helicoptering. Fledge (their first flight) could happen at any time!

Moorings Park has gone all out with good cameras and a split screen so we can see all the action.

Jackie and Shadow were bringing in sticks and working on their nest in Big Bear Valley on Sunday.

A little windy up at the Glacier Gardens Bald Eagle nest where eggs are being incubated. Looks like some branches have been trimmed so that the camera view of the new nest (as of 2022) is much better. Thanks, Glacier Gardens.

Adults with nice crops keeping a watchful eye over the energetic Cal falcons. That big female sure likes to be out of the scrape. I do not envy Lou and Annie when these three start running around!

Annie has been chasing them about to feed them. SK Hideaways caught it for us.

The Decorah eaglet was really hot today, using panting to help stay cool. Little sweetheart. Doesn’t look like they have had any of those bad storms (yet). Hopefully not.

Whenever you see a nest with three equally healthy raptors on it, just smile. As you are all aware it is not easy. The three at Denton Homes are thriving.

The three at Dulles-Greenway are equally doing well. It is difficult to see if the river is flooding and hard for Martin to get fish but there does not appear to be a shortage of prey. There is also not a shortage of plastic bags! The one black one on the side fooled me one day…at first glance I thought it was one of the eaglets hanging on for dear life!

We have a reminder from Liz Bracken. You will recall that Blue NC0 and Laddie LM12 laid the first egg with Blue 33 and Maya quick on their talons. Well, we will be on hatch watch for both of those nests starting on the 11th…yes, that is 3 days a way.

Blue 33 keeping Maya’s he3ad dry in the drizzle.

It is my favourite nest and it always will be. Steady and reliable. Big Red and Arthur, the Red-tail Hawks calling the Cornell campus in Ithaca, New York their territory.

M2 working its way out of that shell.

If Big Red and Arthur’s kids go hungry there is something very wrong in the world.

Big Red tucking M1 in and we can see M2’s egg tooth working away.

Cuteness!

It started raining at the nest of Big Red and Arthur Sunday evening. Big Red seems to always know and she gets her chick/s fed to the brim and then plunks down on them so they are dry and warm.

M2 is here and already being fed! It is sitting in its shell!

Lots of baby falcons about these days….tis the season!

It is just a gorgeous landscape at the Charlo Montana Osprey platform of Charlie and Charlotte. One egg as of yesterday. Thanks, Loretta!

‘H’ reports sad news coming from Hob Osterlund in Kauai. Not large pieces of plastic, tiny micro plastic that will impact all the seabirds including the Royal Albatross, too…what a shame we cannot get a handle on this nasty stuff that is everywhere.

Murphy’s baby is continuing to do very, very well.

Chase and Cholyn’s eaglet at Two Harbours was so full today from eating half a considerable fish that it could hardly walk on the nest. Check out the last image of the three; Mum had a huge crop, too! It was a fish fest day!

‘H’ reports that there is a second egg at Kent Island Ospreys this morning. ‘H’ and I are keeping our eyes on the ospreys at Osoyoos in the hope of identifying them to see if it is Soo and/or Olsen or a new pair.

This sub-adult eagle got a second chance at life because of a rehabber!

For everyone who reached out to help on the Dale Eagle chat and felt shunned and ‘well, abused’, there are some changes coming.

Thank you so much for being with me this morning. Take care. See you soon.
