A piece of lead the size of a grain of rice is enough to kill an eagle!

We really do have to spread this information to those that do not read bird blogs or belong to groups advocating for the banning of all lead in hunting and fishing equipment. Since the fall when hunting season began, wildlife rehabbers have, on their FB pages, testified to the huge toll lead takes on Bald Eagles. It isn’t just eagles – other raptors show up with lead poisoning, too.

I am going to attach the article that my friend sent to me about the use of copper bullets instead of lead. It is a really good read and after trying to take out the good bits and deciding they were all good, I hope that you can read it. I have been able to enlarge it as wide as I can.

The article makes it very clear that they are not against hunting. They simply want the hunters to reflect on their practices and change to ammunition that does not harm or kill wildlife. The return of the Bald Eagle after them being almost completely wiped DDT is being ‘stunned’ by the deaths caused by lead. There is an alternative: copper. There is another and that is stainless steel. A supplier in my City has the stainless steel and copper bullets priced at $1.50 a box more than lead. I do wish they would just stop buying the lead.

Today, Badger Run Wildlife Rehab posted the following information. I am copying and pasting it here to add to that included in the newspaper article. We can never get enough information and clarification!

“HOW are Bald Eagles exposed to the lead, which leads to their poisoning?

Lead “toxicosis” occurs when a bird ingests lead. It’s a neurotoxin & at low levels leads to lethargy often where the bird does not have the energy to find food & simply dies of starvation. The more lead present in the system the more pronounced the symptoms can become including confusion, respiratory distress, convulsions, organ failure, etc. And it also depends on the individual bird. We have had a hawk test very low for lead in the blood (only about 6 ug/dL), but have severe symptoms which resolved following treatment.

There are 2 major ways lead gets into the environment where birds eat it. First, you have the waterfowl (especially swans, ducks, geese) that eat “grit” to help digest their food. Sometimes that grit contains leftover lead shot from 20+ years ago when lead ammo was legal for hunting waterfowl. Other times, it comes from lost lead fishing tackle/sinkers. These birds not only suffer lead poisoning, but predators that eat them also ingest the lead in their system. That 2nd group of birds that commonly suffer lead poisoning includes the birds of prey that eat animals that are tainted with lead. So other than eating tainted waterfowl (eagles, especially) these birds eat mammals that have been tainted with lead. Any gut pile left behind above ground by a hunter using lead ammo has left a yummy lead poisoned meal for any bird of prey finding it. Likewise, anyone shooting small mammals like gophers & prairie dogs with lead who leaves these carcasses above group also is leaving poisonous food for birds of prey.

Can mammalian predators also get lead poisoning by eating left over lead ammo? Yes, but mammals usually have much less acidic stomachs which makes them better as digesting lead particles before they pass through their guts. Birds also have “grinding stomachs” that further help to deliver lead to their bloodstreams.

A piece of lead the size of a grain of rice is enough to kill an eagle!”

You can find more information at http://huntingwithnonlead.org/index.html

Birds like Loons and Swans also suffer a very high incidence of lead poisoning because they ingest the lead sinkers that break off of fishing tackle. Geese and ducks have been protected with lead ammunition being banned they would skin the lead pellets off the water and eat them!

There are many hunters who are supporting the ‘Ban the lead Movement’ and spreading good information educating the general population. You can help, too!

All of the eagles and all those fluffy little chicks thank you for helping them! As well as the waterfowl who ingest all those lead sinkers!!!!!!!! Remember it is an easy fix.

Thank you for joining us this morning. All is well with Ervie. Him and Dad are spending the night on the barge at Port Lincoln and the camera appears stable! Take care. Oh, and before I forget, Dyson and all the garden gang want to wish each of you a very happy Valentine’s Day.

Ervie gets the breakfast fish!

The fish arrived on the nest at Port Lincoln at 6:35:01 and immediately Ervie was mantling it.

Needless to say, Ervie really is the boss of this nest and for good reason. He has fabulous survival instincts.

As you know, my interest is in third hatches and how well they do on nest and off. It will be very informative on how well Ervie does when he leaves the area of the nest seeking out his own fishing spots.

Bazza and Falky might wish that Ervie would fly off and not return.

I only commented once but watchers were calling Falky ‘Mellow Yellow’. It is time that Falky was not so laid back. Yesterday, Bazza took the second fish while Falky had the fish tail from Ervie’s earlier breakfast. If I missed Falky getting a fish, I apologize. It would be good if each had one fish per day. They are all well-feathered and Bazza and Falky will fledge when they are good and ready. e

Oh, wouldn’t it be wonderful to watch Ervie learn how to fish?

At 7:43, Ervie is still eating but his two siblings are hanging close hoping to get some leftovers.

Ah, and Falky got it. Well done, Falky.

If you missed Ervie’s fledge, here it is again. It is quite beautiful on the take off and fly by but the landing was not impressive! Still, I applaud our third hatch lad. Ervie, you are amazing. You are definitely the leader of the pack, so to speak.

If you missed Victor Hurley’s Q & A discussion, it was really really super. I posted that link in my blog, Ervie Flies! early this morning. Very informative and you can start and stop it as you like. If you are interested in falcons or Australian birds of prey – it really is a talk not to miss.

Since the shut down of the 367 Collins Street camera, I hope that many of you are filling that gap with Yurruga in the water tower scrape of Charles Sturt University at Orange. As a former academic, we do not like to comment on others’ research. There were a couple of questions to Victor Hurley about the scrape at Orange and he answered in general terms. Someone asked about the low hatch rate and the eggs. VH said that if the eggs are too large (and he does not know that is the case at Orange) it is hard for the chick to kick them to create a crack all around the egg. He also noted that sometimes eggs get turned when a beak is protruding and the chick cannot right itself if the egg is turned around. Of course, VH said that those are general statements and not specific to Orange. He did comment that Yurruga gets all the food while the four at Collins Street had less bites per chick. He also noted that the Collins Street Four developed quite fast this year and that Yurruga appears to be developing normally. So, she is 8 days younger and the amount of floof she has is normal for this stage.

One of the things that I took away from VH’s discussion was how adaptable Peregrine Falcons are. If there is a drop in numbers of a prey item, they will move to something else. For example, some Alaskan Peregrines have been known to eat trout. The image below was shown as an example.

This year I noted a drop in the amount of pigeon delivered to the scrape at Collins Street. This could, according to VH, be a result of the several lockdowns they have had due to the pandemic. Less people eating their lunch and feeding the pigeons. He did note that the male did bring in Quail and Rail. The falcons normally have a 5 km hunting range but are known to go farther. The are for Collins Street is prey rich. The red dot indicates the site of the nest box.

The falcons do not spend a lot of time on the ledge after the eyases fledge. There is a good reason for this – parasites.

As we learned with Grinnell, the male at the University of California – Berkeley Campanile scrape, birds can become loaded with parasites and they might not be able to protect themselves as well as if they were healthy. Grinnell was taking anti-parasite medication to overcome this. We know he is improving and will be released shortly.

One of the most interesting things to come out of this talk had to do with how the females are attracted to a mate. VH said that there are ‘stunning’ Peregrine males. You and I have seen them. They have an almost orange cere and legs. Dark black, really black, hoods with cream chests and very fine pinstripe chests. Those are the extremely healthy males and the females want healthy. Pale yellow indicates unhealthy. So now when you look at a falcon you can tell healthier vs not so much.

Also falcons divorce. If the female hooks up with a male and he does not share incubation duties or bring in prey, she will move on the next year. The male stays with the nest but it could be in a prey deficit area. At any rate, it was a real good discussion! It is nice to listen to the expert in the area – even talk about rodenticide.

Little Yurruga is doing well. She was working on her breakfast the last I checked.

My daughter went to the Assiniboine River for a walk and discovered about thirty-five ducks still on the river. She sent some photos for us. She noted that there was at least one other group this size down the river.

There are a lot of signs on our park ponds not to feed the ducks and geese or they will not migrate. My daughter ran into a neighbour that says the ducks stay at that part of the river year round and people feed them. They added that parts of the river in that location have been open – not frozen over. I sure hope that is the case this year! There is also an American Bittern hanging around one of the creeks. Maybe they know that this big snow is just to scare us into thinking it is going to be a horrible winter and it will be mild. We wait to see.

The garden birds have found the seed left on the deck and Dyson has, of course, been helping himself. I missed getting him hanging upside down on a suet cylinder. The migrating birds are all gone from this area. Thankfully.

Dyson always knows when the food comes out!!!!!!!!!!!!!!!

The feeders – and there are many different kinds – are all full. It was interesting to me that the sparrows did not mind standing on the snow. According to my daughter, the ducks really like being in the water and not having their paddles on the cold ice.

It is a good day to be inside!

Thank you for joining me today. There could be another fledge at Port Lincoln and we know there will be lots of prey for Yurruga. Take care everyone. See you soon.
