Come and check out Life in the City's new Foundational Reading page! It has recommendations for a wide range of individuals interested in urban ecology & urban evolution. From textbooks and taxa-specific research to non-academic books, urban field guides, and even a couple of books for the young, budding ecologist! Scroll to the bottom of... Continue Reading →
Urban Evolution at SICB 2023
The annual meeting of the Society for Integrative and Comparative Biology (SICB) is here! From January 3-7 biologists will convene in Austin, Texas to share the latest and greatest from a broad range of research areas. Urban evolution talks have a strong showing at the meeting this year, and we would like to hear about all of... Continue Reading →
Urban Observation: Go fetch!
Check out this fun-loving gull and its new toy! https://twitter.com/GarethUnwin85/status/1597610347212734464 This gull seen last week at Queen's Park in Brighton, UK, seems to have been enjoying a game of tennis! Gulls species are notoriously difficult to differentiate. There are more than 50 species of gulls, the majority being part of the genus Larus. If observing... Continue Reading →
Urbanization and the Avian Endocrine System
In a previous post titled Meta-analysis of Urban Bird Phenology, we discussed how urban conditions have affected the average value of phenology and reproductive phenotypes in bird species. Capilla-Lasheras et al. found that urban bird populations had lower values than their non-urban conspecifics for three life-history traits, indicating earlier lay dates, smaller clutch sizes, and...

Urban Observation of the Week: Eastern Grey Kangaroo
Check out these dueling kangaroos in a park in Australia's Gold Coast region! New Yorkers are used to seeing squirrels and rats roam around, but Australian residents sometimes encounter much larger mammal species in their cities. There are four species of kangaroos that occupy different ranges across the Australian continent. The Red Kangaroo, Macropus rufus, is... Continue Reading →

Urban Observation of the Week: Red-Tailed Hawk
Check out this Red-Tailed Hawk going dumpster diving in Morningside Park on Wednesday. This resourceful hawk didn't hesitate to dive in and search for an afternoon snack, along with a shopping receipt! The hawk appeared very comfortable hopping in and out of the trashcan without injuring its wings. Perhaps this is a new behavior to... Continue Reading →
Meta-analysis of Urban Bird Phenology
Humans have significantly impacted environmental conditions and landscapes for several decades through our urban expansion. These changes have produced selective pressures different from those present in non-urban areas. In response to these selective pressures, many species have diverged in physical, behavioral, and reproductive traits between their urban and non-urban populations. In addition, urban landscapes are... Continue Reading →
