Ethics of feeding songbirds

This was the species I had in mind.

Are the ones we got landed with in Cape Town. Once brought in because they were cute … now everywhere there are (equally invasive) pine trees for them.

I’ve definitely been trying to plant as many native flowers as I can to help the birds, and I don’t really fuss too much about dandelions. Its always fun seeing finches going after dandelion seeds. Heck, I don’t even bother with a hummingbird feeder, between the natives I’ve planted and my neighbor’s rose-of-sharons (gross) the hummers straight up ignore the feeder.

I will say, whenever I manage to attract a flock of starlings is usually when I take the feeders down for a week or so. There’s not much I can do about the house sparrows, unfortunately, but I can at least keep the starlings from bullying my native backyard birds.

Dependency on humans might be more accurate. (Is that our diverse biosphere I hear sighing?)

I’m so sorry my writing was not clear enough on that point for you. Yes, certainly, on humans. I think I called them “people”.

My apologies. Just a little dark humor there.
(I got your point)

So, I’m the only one worried about the risk of more songbirds? :-)

No worries, it is entirely possible that you are in fact wildly hilarious and I am just too tired to recognize brilliant humor; we have been rising at oh-dark-thirty for so many mornings in a row (Copa Mundial).

Considering North America is seeing long-term losses across virtually all groups of birds, I don’t see that you have much to worry about.

Coming in here with the mandatory no-fun-allowed to remind everyone that touching wild mammals is generally quite inadvisable since they carry a whole host of easily transmitted diseases (Leptospirosis, tularemia, plague, etc.) along with lice, fleas, and ticks that can give you even nastier infections. (Birds are less of a problem from a health perspective as long as you are careful with habitation.)

In addition to what else has been said, these small birds (titmise and chickadees) are harmless if they are “harassing” you. Any habitually-fed mammal can possibly harm you, your pets, and/or your property, not to mention disease spread to humans and pets. I have a similar location with signs posted advertising that the birds are habituated to being fed. However, when I went to feed them by hand earlier in the fall, they did not come because there was plenty of natural food for them.

We have found ways to “responsibly” (depending on who you ask) feed game mammals, such as deer, with feeders on private property or food plots on gamelands. These practices may or may not be ethical and/or safe for the animals (we feed corn diets to deer we want to hunt because they get fat…), but they are encouraged and managed by wildlife agencies.

I attended the IUCN Iguana Specialist Group annual meeting this month and listened to a talk by researchers studying Cyclura iguanas on islands where they are fed as a tourist attraction (I don’t have a paper to link to since it’s not yet been published, sorry!). These iguanas were monitored physiologically before the pandemic and after the shutdown of tourism to these islands. The iguanas were being fed grapes by tourists and were pre-diabetic and much larger than non-fed iguanas. After humans stopped visiting, the iguanas transitioned back to a more natural diet, and they became healthier. These researchers are trying to find a way to allow this tourism to the benefit, rather than detriment, to the iguanas that are fed. (Iguana feeding can’t stop in totality and would never be outlawed because the economical benefit is just too great for the locals.)

TLDR; The takeaway here is that, like others said, we can feed these small songbirds a “natural enough” diet that isn’t to their detriment. They definitely do not depend on humans for all of their food. They are also harmless to us. They definitely won’t kill your dog because you taught them to get close to you or your home.

Larger birds, however, are a whole different topic…

There’s a metropark near me where I once witnessed a family feeding a raccoon. Definitely not everyone realizes the sorts of diseases that wild animals can spread, especially mammals

Yes! When people feed waterfowl repeatedly at the same place, some food drops down. Over the course of the feedings the food and action can lure turtles, especially snapping turtles. These will wait below for a tasty duckling or cygnet. Some “survive” the turtle attack with damaged legs, leaving them vulnerable to others predators. Happens often in public parks, even with appropriate signage.
