When we see wildlife in our neighborhoods, it seems like we hit the lotto. They are rare gems to spot and even get a picture. Most of the time, we are happy to see them. However, when people let their cats roam freely, the cat can encounter wildlife that may be less than friendly. Recently,... Continue Reading →
Where Have all the Animals Gone: Urban Organisms in the Time of Corona
Like many of you, I've been working from home due to the Coronavirus pandemic. My University suspended face-to-face classes two weeks ago and closed the campus to all nonessential personnel on Sunday night. Knowing this was coming, I packed up my desktop, hard drives, and essential books, and brought them home with me and got... Continue Reading →
Urban Observation of the Week: Caddisflies Under Ice
During the winter, snow covers the ground and lakes freeze. The trees have lost their leaves, the birds flew south, and the bears hibernate. But where do the bugs go? Some also go south for the winter, like the Monarch Butterfly. But others actually stay in the north and are aquatic, living under the ice.... Continue Reading →
Urbanization Influences Pollinator-Mediated Plant Reproduction
If you’ve been following this blog, you’ll know that urbanization has an impact on the ecology and evolution of species. However, we know much about how urbanization affects species interactions. For example, plant-pollinator interactions may be particularly sensitive to urbanization because both plants and their insect pollinators have been shown to respond to urbanization positively...

Urban Observation of the Week: Rat Enjoys Bird Feeder
Bird feeders are a great way to attract birds to your backyard, but what happens when your bird feeder also attracts unwanted pests? The Helsinki Urban Rat Project recently tweeted out a video showing a rat feasting on the spilled grain from a bird feeder. Check out our other posts on urban rats here and... Continue Reading →
Video Recommendation: The City Animal Tier List!
The YouTube channel TierZoo makes a ton of cool videos about animals, specifically viewed through the lens of gaming, where they rank different animal species according to how successful they are at living in different habitats. Past videos have included lists of dinosaurs, sharks, and cats. However, I was recently thrilled to find they had... Continue Reading →
Urban Observation of the Week: Ladder-backed Woodpecker
Do you enjoy spotting urban birds but need some help with identifying what you find? This is something I constantly encounter (often with family members sending me photos and videos for identification). Luckily, the Cornell Lab of Ornithology has a fantastic guide to help you. A few weeks ago my brother sent me this video... Continue Reading →
Ants in France: Urbanization without Isolation
In ecological studies, ants are commonly used as bio-indicators because they are able to respond to rapid changes in their environments. This also makes them a great system to use in urban studies given the rapid changes that urbanization poses on ecosystems. However, there studies that look at the evolutionary patterns of ants in response... Continue Reading →
Urban Observation of the Week: Fox and Magpie
It is getting wild in Scotland cities! Last week we brought you canal otters of Edinburgh and this week we bring you a fox and a magpie in Glasgow. A bit of shrubbery between a car park seems to attract several urban wildlife creatures. Do you have a photo or video of an urban species... Continue Reading →
Toxic Toads in a Toxic World
The Common European Toad, Bufo bufo, is a pond-breeding amphibian found throughout Europe, including in urban environments. Ecological changes (e.g., predator communities) in anthropogenic habitats present novel challenges to the common toad, but abiotic changes (e.g., pollution) may also influence phenotypes in these landscapes. Nevertheless, we know relatively little about how these urban-dwellers (and specifically their toxins)... Continue Reading →
Urban Observation of the Week: Canal Otters
We usually find otters in rivers, so you might not see one unless there is a river that runs through the city. But sometimes, we create our own rivers via canals and wildlife can occupy these man-made rivers. This female otter was spotted in the Union Canal in Edinburgh, Scotland. Do you have a photo...

European Rabbits Have High Gene Flow in German Cities But Not Other EU Cities
Many organisms seem to do poorly in urban areas, and it is unclear which organisms will become extirpated in cities. Typically, organisms that are experiencing population declines are ones that we would think are negatively impacted by urbanization. However, this may not always be the case. Recently, Ziege and co-authors studied populations of the European... Continue Reading →
Urban Observation of the Week: Woodpecker in Washington Square Park
Last week we brought you a bald eagle in Manhattan, this week we present you with a woodpecker found in Union Square Park in NYC. Urban birders win again! Parks are a great refuge for many organisms that find themselves living inside the big cities. Check out the other animals found near Union Square Park.... Continue Reading →

Urban Observation of the Week: Bald Eagle in Manhattan
Thanks to the collective efforts of urban birders, we have been able to bring a suite of urban observations of birds. Here is the majestic bald eagle, hanging out in a tree in the East River Park of Manhattan, NY. Do you have a photo or video of an urban species doing something unusual? What... Continue Reading →
