Facts: Pigeons were likely the first tamed bird around 4500 BC
They are super comfortable around LOTS of people as we are a source of their food and construction of their habitat in skyscrapers
Pigeon poo is highly acidic and is known to be corrosive
It can cost tens of thousands of dollars
I’m not even going to bore Austin with the details on what it takes to clean up this mess
Contamination from droppings leads to tons of fines
Which makes me wonder if its a government building, the taxpayers are most likely to be the ones to pick up the tab
But just because you see pigeons in your backyard does not necessarily mean its the sign of bird end times

According to the University of Wisconsin there are three classifications of birds today
Listen up Back Porch Birders! Think about the following categories I’m about to read off and figure out which ones you think you can attract to your feeders
Adapters, Exploiters, Avoiders
Researchers from the University of Washington say as forests turn into subdivisions, certain species of human-shy songbirds – dubbed “avoiders” – are losing their mates as they flee for more propitious territory, causing some to miss as much as half of their breeding years
Adapters are birds that take advantage of the new foods and nesting opportunities that exist in suburban settings.
“It is we engineers who hold most of the keys to the solutions of the world’s environmental problems” – Lt. General Henry Hatch
Exampleof how prolific the army core of engineers are from the past and to today
1990-1991 included roughly $1 billion for environmental restoration projects, which ranged from hazardous waste cleanups at military bases to the creation of wetlands.
Environmental enhancement and restoration projects comprise one-third of new Corps projects (including reconnaissance “surveys”) proposed for FY 2004 (U.S. Department of the Army, 2003).
Ecological engineering is relatively new
Ecosystems are inherently self-designing, and restoration efforts should recognize this process through the application of sound environmental engineering principles. Traditionally, restoration efforts have focused on improving land and water resources for specific plant and animal species and have not taken a holistic approach to planning and management.

What does Hitchcock’s movie The Birds have in common with the closing of all Mississippi beaches?
Blue-green algae blooms have invaded Mississippi beaches
Cyanobacteria are toxic blue-green algae blooms which threaten most of what it touches
green when metabolising and turn bluish when the scums are dying
Hard to identify one toxic algae bloom from another
domoic acid and BMAA (a neurotoxin) are released as the bloom dies and the cells become . Domoic acid has been implicated in serious food poisonings, even deaths associated with shellfish and BMAA in neurodegeneration such as Alzheimerâ€™s disease, ALS (Lou Gehrigâ€™s disease) and an ALS/Pakinsonism-dementia complex of Guam (Guamâ€™s disease).
Santa Cruz August 17 1961
In the early morning hours of August 17, 1961, residents of Santa Cruz were invaded by a massive flight of sooty shearwaters slamming into their homes and littering the streets and town. The Santa Cruz Sentinel Sentinel reported the incident under the headline; â€˜Seabird Invasion Hits Coastal Homesâ€™
Hitchcock later called the paper letting them know that he was going to use the newspaper article for research.Â It is said that the movie The Birds was going to be shot in England but Hitchcock was so inspired by the event he shot the movie in California.
Now what do toxic algae blooms have in common with Du Maurierâ€™s book The Birds and Hitchcockâ€™s famous adaptation?
It is said that the Sooty Shearwater attack was due to toxic blooms from algae.
Evidence for a role for algal bloom poisoning in a mass disorientation and death of sea birds was presented in 1991, when a similar incident of unusual bird behaviour was observed around Monterey Bay in California. Studies of the dead birds, including brown pelicans and Brandtâ€™s cormorants showed they were poisoned by domoic acid, probably from the anchovies that the birds fed on.
Scientists believe the algae feeds off of nitrogen from agricultural runoff which is also the number one water polluter
How long will this last?
Until the spillway is closed.Â Hurricane Barry will prevent the spillway from closing preventing freshwater from entering the Mississippi.
Congrats to Sarah Winnicki on defending her thesis!
AOS is going on in Alaska right now and if any listeners are there I hope you checked out Dylan Smith’s poster about the effects of drought on grassland birds, great info, great visual, and my name is even on it!
I used a Nikon d7200 and sigma 100-400mm contemporary lens.
I did my first bird count this past December for the Christmasbird count. I had plans for big day already. Y’all still did inspire me to go out even in the inclement weather lol. The winds were up to 60mph and torrential rains. I logged 20 species before I ended because of the weather. I did see a common loon that should have left already but hasn’t and is still in the area.
In the News
Feral Parrots taking over America(Gizmodo)
56 parrot species living in the wild across 23 U.S. states. Of those, 25 species have formed breeding colonies
How do scientists know?
The researchers determined that a bird population was “established” if birdwatchers had observed the species 25 or more times (a purposely high but relatively arbitrary number) and if records included observations of breeding
monk parakeet accounted for more than a third of the observations, while red-crowned Amazons and Nanday parakeets accounted for 13.3 percent and 11.9 percent of the sightings
Monk Parakeets are particularly good at surviving in human-altered habitats.
Advice? Suggestions? This simple feeder is the only one I have. We have a pair of cardinals that enjoy it and I’d like to keep them! However, everyday when my husband gets home from work he removes the feeder because by evening time there will be more than 10 doves and probably more than 20 sparrows and now cowbird too – all sitting in the Crepe Myrtle tree or on the ground under it. They are noisy and busy. My husband worries they annoy the neighbors. I’d rather just encourage our cardinals! What to do?
What would Austin do?
What would Tim do?
Feeder Activities- Preparing for Summer
Keep your seed dry.
to prevent mold
Change thistle seed every couple of days
Oils dry out and birds won’t eat it
Move feeders occasionally.
bacteria can spread from seed hulls and bird droppings
Put suet in the shade.
Change out Hummingbird nectar every couple of days
