Evolution in an Urbanizing World
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 →
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 →
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 →
Throughout the city of Toronto, there are a number of old canoes that have been repurposed as pots to grow plants. In fact, several have milkweed planted in them to help local pollinators. Now that we are in the middle of winter, only the stems remain. Can you identify what was planted in this canoe?... Continue Reading →
When you live in the outskirts of the city, every once in a while you may spot a bobcat in your neighborhood. In fact, we have had a few urban observation posts of neighborhood bobcats. But how are these urban bobcats fairing compared to ones that stay in their natural habitat? Recently, Kozakiewicz and co-authors... Continue Reading →
Milestones and more In 2019 we hit a lot of milestones. We turned 1 year old. We were featured in several major news outlets, including as a News Feature in PNAS, the Wildlife Society, and Wired Magazine! We reached over 13,000 visits since starting from (almost) every corner of the globe (we're looking at you,... Continue Reading →
Many people imagine a pristine desert in the Southwest US, with the iconic saguaro cacti in the foreground, mountains in the background. In recent years, these deserts have become highly urbanized. Thankfully, there are protections in place for these majestic, century-old cacti. If you plan to build where there is a saguaro, you have to... Continue Reading →
Now that winter is upon us, it may seem like there is less urban wildlife around. But there's a chance to spot some really cool mammals like the one for this week's observation. Here we see a bobcat in a back alley chasing a hare! Thanks to LITC contributor Mason Stothart for catching this tweet!... Continue Reading →
In Mississauga, ON, Canada, we have a slew of different birds that cause a nuisance. I'm sure most of you know about our geese, they are mean and will chase you down the street if you get too close. There haven't been many pigeons in my grocery store parking lot, probably because these shorebirds are... Continue Reading →
With the US Thanksgiving tomorrow, here's a turkey treat! Wild turkeys were found earlier this month terrorizing Holiday City, a New Jersey neighborhood. Wild animals can be dangerous, so keep your distance. Sadly, packs of wild animals get pushed into urban neighborhoods as we continue to develop our cities on their territory. They can cause...

Entomology 2019 I recently attended the Entomology Conference in St. Louis, Missouri and here are some of the highlights. I was part of the special symposium "What Everyone Ought to Know about Insect Biodiversity in the Urban Environment" where a number of scientists gave talks and posters about their research related to this topic. Biodiversity... Continue Reading →
Here we go again NYC, urban birds! I am always amazed at how many of our observations come from NYC. Before this blog, I had thought that such a large city would only support pests, like pizza rat. Here's a pair of hawks nesting near a clock tower in Marcus Garvey Park (Harlem). A special... Continue Reading →
As the largest city in the United States, New York City seems to be full of all sorts of urban wildlife! This week, we bring you the smoking cockroach. If your pesticides won't kill it, neither will smoking cigarettes. Urban birds are known to incorporate cigarette butts into their nests, which may function as... Continue Reading →
Recently, I published a review paper in Molecular Ecology with my co-authors, Ruth Rivkin, Marc TJ Johnson, Jason Munshi-South, and Brian Verrelli. In this paper, we discussed how urbanization influences gene flow and genetic drift. We looked at 167 primary literature papers to see what researchers have found. Competing Models of Urban Effects You might... Continue Reading →
If you have ever been to the desert Southwest (of the USA), you have probably noticed spider webs throughout the summer and even in early fall. And even if you have not noticed the webs, you'll likely have seen leaves that look like they are floating in the air, which is really leaves stuck in... Continue Reading →
