Is science a match for the pathological passions of the bighearted but monomaniacal people who maintain outdoor cats? We talk with the Urban Wildlands Group‘s Dr. Travis Longcore, whose critique of “trap-neuter-release” (TNR) is still one of the best out there, about the threats cats pose to wildlife, what works and doesn’t work to control outdoor cats, and the Urban Wildlands Group’s fight to use science to guide Los Angeles’ cat control plans.

Urban night life isn’t just about bars, clubs, and theater. When night falls, the bugs fly. Tag along with Billy and Ken Frank (author of the Ecology of Center City Philadelphia) as they have a moth night in Billy’s community garden. Billy also talks with ecologist and insect researcher Stephen C. Mason Jr. about how the pros do it and why bugs fly to lights in the first place.

Do you like pumpkin pie? Thank the pollinators who make squash (fruit of members of the genus Cucurbita) possible. But don’t thank a honeybee, look to the squash bee, Peponapis pruinosa, a solitary bee that, centuries ago, followed the original spread of squash cultivation by Indigenous farmers. Billy talks with Penn State evolutionary ecologist and bee expert Margarita Lopez-Uribe, whose research has tracked the squash bee’s spread by studying their genes.

What does the non-human community of a city look like? Is it the same species everywhere (pigeons, dandelions, bridge spiders, yawn) or does the wildlife from the surrounding area show up? We hear from Dr. Misha Leong of the California Academy of Sciences to hear about biotic homogenization in cities AND how she used data from the City Nature Challenge for the study she co-authored along with Michelle Trautwein (note that this is a pre-print and has not yet gone through peer review). Also LJ Brubaker of Bartram’s Garden in Philadelphia joins us to argue the case for native hymenoptera and talk about their park’s plans for the 2019 City Nature Challenge.

Tony and Billy are back after a hiatus, talking about Tony’s new house next to a trail head and the urban raptors you happen to see while counter-protesting fascists. Then (at around 27 min) we hear from Dr. Cynthia Skema the Mid-Atlantic Megalopolis Digitization Project (best-named citizen science project ever). MAM Digitization is taking herbarium records from New York to DC, scanning them, and making them more accessible to researchers. You can pitch in by reading and typing up the tags – a great way to help science along while connecting with past naturalists.

The 2019 City Nature Challenge is a competitive urban bioblitz. Tony and Billy talk about the CNC and Philadelphia’s plans after talking about Tony’s new rescued cat (about 15 min). We also go through a grab bag of fun urban nature topics:
The fire salamanders of Oviedo: Check out this video and read up on their population genetics.
Black-bellied hamsters of Vienna: “…if you get too close, they fight you like a bear.”
Wild boar: goring a commuter in Japan and getting slaughtered in a Berlin parking lot
Otters in Singapore: photobombing a marriage proposal.

What do we owe the animals that live around us? Do we spend money on animals when there are humans in need? Do we feed animals to animals to save animals? We tackle the tough questions as we wrap up our series on wildlife rescue and relocation with a two-part episode talking to the pros. In part one we visit the Philadelphia Metro Wildlife Center and talk with executive director Rick Schubert and assistant director Michelle Wellard. We see the ugly (a wounded heron) and the beautiful (so many baby possums and birds destined for release). In part two we talk with Subrahmanian Santakumar about wildlife rescue in Bangalore, India and the Wildlife Rescue and Rehabilitation Centre.

Entomologist and urban bee specialist Doug Sponsler joins Billy and Tony early in the morning in a community garden spot in West Philadelphia to observe squash bees and talk about what counts as native. Squash are not strictly native to Philadelphia. They were introduced by Indians before European colonization. The bees followed the squash cultivation from its original distribution. Are they native? How much does it matter?

We discuss research about squash bee pollination efficiency:
We also discuss research about squash bee range expansion as they followed expansion of squash cultivation:

Special (very long, thorough – don’t make this your first Urban Wildlife Podcast episode) Episode: Billy, Tony, and biologist Clint Springer dive into the outdoor cat literature. This is a companion to our Cat Wars episode. Finally we sat down and went through the literature cited by Alley Cat Allies as well as the literature Alley Cat Allies doesn’t tell you about: what is the impact of outdoor cats on wildlife, and what have scientists learned about how to control un-owned cats? We actually changed our perspectives a little bit: TNR is ineffective, but without controlling cat dumping and cat feeding, it is really hard to control stray and feral cats.
Here are the sources we discussed in the order we discussed them.

City lights attract birds to cities where they are vulnerable to windows, cats, and other dangers of city living… or, depending on what we do, they can have a meal and be on their way. Spring migration is a great time to talk with Audubon PA’s Keith Russell about the wonders and challenges of bird migration. We talk with James McLaren and Jeffrey Buler about how artificial light at night (ALAN) can draw birds into urban green spaces. We also hear from Nicolette Cagle of Duke University about their bird-window collision research and the iNaturalist group that lets you contribute (and read more here).
We split the episode into two parts. This is part two.

Evolution by natural selection is happening all around us, all the time, even in our cities. Biologist Menno Schilthuizen, author of Darwin Comes to Town: How the Urban Jungle Drives Evolution, talked with Billy about how species adapt to urban habitat, and about ways that urban evolution might be a different than what we see in more ‘natural’ landscapes.

This year we honor World Sparrow Day with a look at how they got to North America and the Sparrow War of the 1870s that followed. Matt Halley joins us to talk about the weird but true history of exotic bird introductions in the 1800s and the Sparrow War that followed the successful (or catastrophic, depending how you look at it) introduction of the house sparrow. Tony works in another sparrow war half a world away, and we conclude with a reminder not to let dead birds go to waste (and to report them in iNaturalist!).
