When I first saw this photo, it took me a moment to realize that it was not a real person. I guess my thought about scarecrows is the old fashioned Wizard of Oz type. Up in the middle of the field (or yard) with a stick up its backside with arms stretched out to the sides and crows laughing as they feast on corn.
But when it comes to purple martins, scarecrows are quite handy and when I looked at this one posted by Ray Gingerich, a fellow PMCA forumite, I said, “Now THAT’S a scarecrow!”
Ray describes his use of his scarecrow:
“As an experiment I put this fellow on duty all summer (24 hour duty and not one complaint from him). He didn’t have much affect on sparrows but seemed to have some affect on starlings and hawks. I had a few starlings this spring before placing Joe on duty but none afterwards, when I placed him near my barn and partially hidden from the sky I had a few low fly bys from hawks, if I placed him out in the open near the bird houses the hawks seemed to pass by at a greater distance. I kept moving him to different locations in my yard and repositioning his arms & legs.
Couldn’t get keep him awake though, wonder if the sparrows could tell.”
Did you hear that? It is the sound of my soap box being pulled out of the closet and dusted off. I have been wanting to write about a very big pet peeve of mine for some time…so now that my birds are gone, here goes.
As a birder, it goes without saying that I am a conservationist. As a purple martin landlord, that just adds fuel to the fire and makes me even more pig headed when it comes to the house cat being outdoors. First off a few facts MUST be cleared up.
Fact #1 Cats are domesticated animals-not wild. Many people consider letting their cat room outside as an extension of the cats native environment. They consider it cruel to keep cats indoors. When actually the opposite is true. Cats were domesticated some 4,000 (four THOUSAND) years ago. They do not occur naturally anywhere. They have only been in North America since European Settlers arrived.
Fact#2 Cats hunt and kill whether or not they are hungry. Studies show that well fed cats actually kill MORE than feral cats. In other words they hunt for pleasure. The portion of the cats brain that is used to hunt is not the same part of the brain that registers hunger. Thus a cat will hunt even if it just ate a huge bowl of food. They hunt to kill, not necessarily to eat. Also neutering and spaying have no impact on a cats desire to hunt.
Fact#3 Studies have shown that Bells do not keep cats from killing. On the contrary bells may actually make cats more successful at hunting. Besides the fact that a bird does not necessarily associate the sound of a bell with danger, bells teach a cat how to hunt even more efficiently. The cat will learn how to move silently. And bells are of no help when a nest full of helpless nestlings is being stalked. Consider this product called the CatBib. Their website has a study that was conducted that shows an 81% decrease in the amount of BIRD KILLS! That is impressive. Unquestionably more effective than a bell this device allows the cat free movement, is soft, flexible and lightweight yet restricts a cats ability to stalk prey.
Fact#4 Cats kill HUNDREDS of MILLIONS of birds nationwide per year. That is no trivial number even though it is a low ball number. According to a post on Windstar.org that estimates over a BILLION birds are killed each year in the US alone. And looking at the math, that number may be conservative as well.
Follows is a sobering quote from www.Windstar.org :
“The American Veterinary Medical Association estimate in 2007 there were 81,721,000 pet cats in the U.S.
According to Cat Fanciers, 43% of cat owners allow their pets to roam outside, that gives us: 35.1 million outdoor pet cats in the U.S. Add the number of feral and stray cats. numbers published by feral cat advocacy groups say there are between 60 to 100 million cats. Lets just take half that number say 81 million.
So that’s 81.7 million + 35.1 million = 116.8 million outdoor cats. More realistic might be a range of 95.1 to 135.1 million (based on possible feral range). But for arguments sake, lets just stick with 116.8 million cats for now.
How many birds killed by cats? According to a study in Michigan by Lepczyk et al, outdoor pet cats across an urban to rural gradient killed an average of .683 birds each week during the breeding season. If you can extrapolate that across the full year, that would be an average of 35.5 birds killed by each cat/each year. If you can use that figure for all outdoor cats, you get a calculation of 4.1 billion birds killed each year.
But maybe cats don’t kill birds at the same rate all year long, or at the same rate everywhere that they do in Michigan. But lets presume that the only kill birds during the breeding season (22 weeks in MI), that would still be 1.76 billion birds killed per year.
Another study in San Diego found each cat to kill an average of 15 birds per year (and 41 other small animals). If you multiply this number by the number of outdoor cats you get 1.75 billion birds killed per year. And that’s just in the U.S. and doesn’t take into account our migratory birds killed by cats in Canada or Latin America.”
Fact#5 Cats are responsible for the EXTINCTION of 33 bird species since the 1600’s. That is more bird species than any other cause, except habitat destruction. Currently there are dozens of seriously threatened birds that are still experiencing high levels of predation due to cats. Ground nesting birds, such as the Piping Plover, Least Tern and California Tern are even more at risk and several monitored nesting sites have been abandoned by these birds due to cats.
So you know all this data and you still feel it necessary to let your cat out. If that is the case, you are placing more value on your cats experiences outside than the animals that it will kill in its time outdoors.
If you think your cats rodent killing is a positive, think about this. Each mouse that a cat kills is decreasing the available food supply for native hawks, owls, snakes and other predator species.
If you believe TNR (Trap Neuter Release) programs work to decreasing the problems caused by feral cats, I urge you to visit TNR Reality Check. This site offers an eye opening reason why TNR programs are a huge dis-service to the community, environment and our birds. Most importantly it show why these TNR programs do NOT work.
The last remaining nest is on the numbered gourd rack. Gourd #6 has 5 nestlings that I have neglected terribly. I had watched the ASY male and SY female feeding vigorously 3days ago. Yesterday I saw no feeding but the racks have been covered with purple martins for the entire morning and well into the afternoon. I was sure that I just missed them. Today I saw two little heads poking out of the front of the Troyer horizontal gourd. I was sure that the nest had been hijacked by a lazy fledgling as the two heads looked so vastly different in ages. So I lowered the rack.
When I opened the gourd I noticed it was pretty dirty, but I had seen worse. I proceeded to take everyone out and put them in the 5 gallon bucket to do a nest change. When I looked at the nestling however, I noticed that 4 of the nestlings looked to be about 20+ days old and the one runt seemed to be lagging way behind. He had the feathering on his body and head of a 16 day old but his flight feathers were about the same length as his nest mates.
On further exam, I found all of them to be underweight. The runt, worse of all and another nestling not to much better. All had an easily palpable keel bone. What is a keel bone? It is the bone in the center of the birds chest that should be surrounded by breast meat. The runts keel bone stuck out like a razor, skin flaky and dry. He proceeded to poop on me but then I saw his large hard abdomen. And when I say hard, I mean hard like a rock. And unless something is made of bone (or cartilage) there is nothing on a living body-human or animal that should be that hard. I kept him out of the nest and replaced the others. A Bot fly? A partial blockage? A tumor? I do not know what his problem is but I am vigorously re-hydrating the poor fellow.
Observing the nest is difficult with 2 young boys getting into everything but I tried to watch for mom and dad martin to no avail. The entire time I was checking the nests, changing, etc, there were no concerned parents flying about. I am beginning to think that an Owl has attacked and flushed the parents out. The nestlings being to young stayed safe in the dark far reaches of the Troyer gourd but without mom and dads care, they will soon expire.
Since Folke Peterson Wildlife Center is closing soon I placed a call to Busch Wildlife Center in Jupiter, Florida. I spoke to the director and if the nestling is still alive in the morning I will take him there. I will try to observe the nest to make sure that the parent/s are feeding. If not, I will remove them all and take them to the rehabber. It can be a case of late nest syndrome (I just made that name up) but all that means is that in very late nests it is not uncommon for one (or both) of the parents to loose interest in the process and slack off.
My first purple martin pair was a ASY male and a SY female. She worked her tail off and he would come by a few times a week. He would sleep in the gourd on occasion but basically left the entire raising of the clutch to her. She successfully fledged her 2 nestlings-all alone- after all the martins were gone.
After my snake debacle some weeks ago, the last thing I want to deal with are snakes in my yard. Yes, I know they are there. Yes, I know they serve a critical and important role in the food chain. I just am still a bit irritated at the red corn snake that got past my predator guard and ate 5 beautiful little featherless baby purple martins. Read the post here.
As I was looking outside I saw a large 4 foot black racer (I call them-no idea as to the sp. name) browsing my patio. It was “looking” in the sliding glass doors and peacefully gliding along. Perhaps due to my husbands mowing of the grass this weekend or the heavy rains that have been a daily occurrence, the snake was making itself quite at home. I was shocked as the snake was by far taller than my sons. I ran outside with a broom and managed to corral the snake under a bucket. Not sure what I was going to do with it, I placed a weight on top and collapsed on the sofa to the delight of my children who had a million questions as to everything. After catching my breathe I called my husband to tell him of my adventure and as I was talking to him a SECOND black snake crawled across the patio. “How did he get out from under that bucket?” was the only question that entered my head as I hung up the phone (without saying bye) and ran out, again with the broom to corral the snake. The snake made a much speedier exit than I made my entrance and I was left empty handed. How did he get out? I lifted the bucket partially only to see the black tail of the snake still under the bucket. The boys are now convinced that the back patio is a snake thruway and I almost feel I am in 100% agreement.
2 snakes in less than 20 minutes. What is going on. I watched the purple martin housing for some 15 minutes to see if anything was out of the ordinary. All seemed normal. The lettered gourd rack seems to attract an abundance of SY’s and HY’s fighting. The numbered gourd rack seems to be the ASY’s favorite and is a much calmer place to be. Gourd #6 must have newly hatched babies as a ASY male and female are busy feeding. A late clutch for sure. I finally relaxed and played with my boys.
About 2 hours later I look out the sliding glass door and again, what do I see??? Yes, ANOTHER large black snake. Now it is getting creepy. Well, fast forward through the broom, roundup and bucket and I now have 2 snakes in a plastic bag…very much alive and well. As soon as my husband came home I took a short drive about 3/4 of a mile down the road and released them.
Yeah, live and let live…just not in my yard anymore.
The deed was finally done. The HY purple martin that was found at the Davie roost was peacefully euthanized over the weekend. With a broken shoulder and no hope of rehabilitation he was put down.
Then yesterday on a non purple martin note, one of my gouldian finches was on the verge of death. Egg bound and with her eyes closed, I picked her up off the cage floor and after almost 20 minutes of warm steam, mineral oil and gentle massage, she expelled the egg. I totally blame myself as I had not been giving her egg shells to eat. Today she is a bit greasy looking but chirping and flying about her cage. I even watched her take a bath.
At the colony here, the purple martins were busy dive bombing a large hawk that was painting lazy circles directly over the housing. I am sure it was on the look out for fledglings. The heat index was well into the hundreds. 110 in some locations and was just miserable. I stayed in and watched from air conditioned comfort.
Apparently the raccoon predation was just too much for the purple martins at the Davie Road Racetrac gas station. They are no longer roosting at that site. I went on Friday night and the few purple martins that flew over head, never came down to the trees. The dead martins on the ground were still there, but no fresh kills. Apparently the roost was abandoned shortly after my visit on Saturday June 13.
Fortunately for all us purple martin lovers, a fellow PMCA forumite “Stingray” was shopping in the area and happened upon the new roost location. It is now located at the “Tower Shops” just South of 595 on the East side of University Drive, in the same plaza as Home Depot. The chances of finding the new roost location is almost a miracle in my book and the disappointment I felt this Friday is now replaced with excitement again. woo hoo! I can’t wait to go and see the new spot. I hope the folks at the Tower Shops greet the purple martins with the same welcome attitude that they enjoyed at Racetrac Gas station. The potential for a negative response is high considering there is no overhead cover to protect any shoppers from the rain of bird poop that they will be experiencing.
I have been ridiculously busy trying to prepare an article for you on emergency care of purple martins…I should say, first responder care of purple martins. I went to Folke Peterson Wildlife Center on Friday and met another one of their wonderful Veterinary Technicians, Faith, who let me photograph the HY purple martin while he was force fed. He is still not accepting food from the hemostats and his outlook is poor. Other than the fact that he is being force fed three times a day and can not fly, he appears calm and comfortable. A perfect gentleman.
Other interesting finds at the Wildlife Center was a Chimney Swift nestling that was brought in recently. Eyes shut and chattering loudly, the little nestling looked so out of place in his box. My heart bleeds for this little guy. For great information on Chimney Swifts and what you can do to help these birds visit ChimneySwift.org I was shocked to find out that contrary to what I had read on the swifts breeding range, South Florida, the West Palm area to be exact, has a nice little colony of swifts that live out my way. I am eager to convince my husband of the need to put up a Chimney Swift tower! I am so excited for this project for next year. Can you imagine THAT on a webcam?
Another interesting patient at Folke Peterson was a juvenile NightHawk. Which is quite the coincidence considering that I recently wrote a blog entry about these illusive birds that I NEVER thought I would see so close. Like a pet rock, it sat in its cage with its big eyes staring back at me. A curious bird and not very bird looking at all, up close. Faith told me of the odds against rehabilitating this bird and all birds that are strict aerial insectivores. A diet that is never fully able to be replicated, humans can only come up with a fair approximation of the dietary needs of such birds. I hope this one makes it too.
As you know, on Saturday I dropped off a HY purple martin that I found at the Davie Roost. The apparent trauma of a tree collision (?) the martin was unable to fly and seemed to be slightly uncoordinated. I brought him to the Folke Peterson Wildlife Center where he was given some medications and observed. Today I received bad news. Apparently after he failed a flight test, he had an X-ray taken and it was found that he has a crushed shoulder. Unable to be fixed surgically, he is doomed; and though calm and comfortable, his days are numbered. I am upset at the news and so looked forward to releasing him back at the roost to join his comrades. I am so sad to think that he will meet the same fate as those that were littering the floor. Another fallen martin, another statistical failure and another purple martin that will never fly across the Equator. I will tell you when his hour comes.
The colony remains busy in the morning but quiet as evening approaches and I am looking forward to going to the roost again. I have been unable to locate any raccoon repellent at the local Lowes, hardware store, feed store, Dicks sporting goods or Bass pro shop. The ideas I have received include moth balls, metal flashing, Vicks vapor rub, large cat (like lions and tiger) feces, traps and chaining a large dog to a tree under the colony. Unfortunately, I have been unable to come through on many of those ideas. The folks at one animal removal service told me that since the raccoons have discovered the richness of the roost, that a chemical/scent repellant will be useless.
Today has to be one of the highlights in my short yet thrilling experiences as a Purple Martin Landlord. Tonight at 7pm my husband and 2 young boys took me to the RaceTrac gas station on Davie Road in Davie, Fl. It was the most spectacular thing I have ever seen. And to think that this roost is SMALL!!! Photos can not do it justice. I tried taking photos and I felt like I was trying to photograph the Grand Canyon with a Polaroid. I can only wonder the splendor of a large roost like those in Texas, Louisiana or Pennsylvania. My husband took a guess and says somewhere around 5,000 birds or so. In a photo I took I counted 200 martins in that small area alone. And the sky was covered with them. I highly encourage any local birders to check out this most amazing show.
On a sad note, as I walked about before the martins came in force I noticed the ground under the trees that the martins are roosting in, was littered with dead martins in various stages of consumption. Piles of feathers, martins with heads chewed off, wings and other bits and pieces covered the grass. I was aghast and at first I assumed that Owls were arriving at night to feast on the martins. That may well be the case but then my husband pointed out the real culprit. A large raccoon scampered across the parking lot and climbed the first tree. It became quite apparent that the raccoons are having a nightly banquet of bird. Of course they don’t have the decency to finish one birds before killing another. I walked from bird corpse to bird corpse wondering what I could do…trust me, I had some crazy thoughts.
As I walked about taking photos I noticed one of the “corpses” was looking back at me. Laying on its back with his head turned so he could see me, a fledgling Purple Martin lay moving his short feet in a bicycle riding fashion. I approached slowly and thought it would right itself in time to fly off, but it did not. I picked him up and gave him a look over. A perfectly alert little HY purple martin. His eyes are sharp and his temper was quick but when I tested his wings he did not seem to even want to flap them. Weak or injured he is now resting comfortably in a dark box with a crop full of mealworms and scrambled eggs. I will take him to Folke Peterson Wildlife Center in the AM to be checked out. If all looks good I hope to return him to the roost to join the other martins.
It is late and my heart is happy so off to sleep. I will post more pictures of the roost in an upcoming blog entry. So check back soon!
The fledglings are clambering all over the gourd racks and the house causing a ruckus all day long. The rain has been falling on and off for the last 2 days and they seem to be enjoying the it. All it takes is me stepping on to the back patio and I set them off in a slurry of purple. The flock moves en Mass except for the remaining parents that are still feeding nestlings. More than half of the nests have fledged and my season will be starting to wind down shortly.
The Red Shouldered hawk is persistently attacking the colony and I can only assume that it has been successful, though thankfully I have yet to witness a successful attack. Yesterday I witnessed 3 such attempts that set the purple martin off in an alarming cacophony. I am sure that now having said that, I have jinxed myself and come tomorrow morning I will see the blasted hawk plucking a martin right before my eyes. Please knock on wood!
I have had so many “firsts” this year. First snake attack. First dead nestling on the ground. First pair to actually nest in the gourd hanging on the 5 foot shepherds hook. First nest check with my son. First time broadcasting the webcams. Never mind all the milestones and “firsts” with the website and blog. I already am missing my birds and can’t wait to show them again next year what a wonderful place this is to call home.
The Red tailed hawk continues to make half hearted passes at the purple martins but I have yet to actually witness any kills. (knocking on wood frantically) I have seen the hawk looking for the mockers nests and perched low in branches looking for snakes and what not. Today’s pass at where the mockers are nesting was too close for comfort. Though I do not think he actually found the nest, he was looking and the mockingbird parents were being brave, if not foolish in their attempts to distract the hawk. Pass after pass the mockingbirds dove his head, a small annoyance to the hawk. The hawks gaze was intense and though I am unsure if he actually saw the nest. It could be that he was not interested in eggs and is just keeping up to date with the happenings in the nest. Perhaps he will return when the nestlings are a more satisfying meal. If the neighborhood crow does not get there first.
The martins are doing well and today I saw Chimney Swifts for the first time. I have heard people describe them as flying cigars before, but today I realized what an apt and fitting description that really is. Almost as if the have no tail and wings fluttering faster than a martins, they twittered loudly. The martins flew about not as interested in the swifts as the swifts seemed interested with them. They stayed, flying about for about 3-4 minutes until finally flying off. Not a very attractive call, the twittering reminded me of the clicking of dolphins. But then again, compared to my beloved Purple Martins, no bird sings as sweet.
