New Lit Alert: Colourful Urban Birds: Bird Species Successful in Urban Environments Have More Elaborate Colours and Less Brown

Juan Diego Ibáñez-Álamo, Kaspar Delhey, Lucía Izquierdo, Mihai Valcu, Bart Kempenaers Juan Diego Ibáñez-Álamo and Kaspar Delhey shared first authors. Abstract Rapidly expanding urbanisation presents significant challenges to wildlife. Consequently, many studies have investigated the impact of urbanisation on diverse organisms. However, despite the ecological relevance of animal colouration, its association with urbanisation remains poorly understood. Using a global... Continue Reading →

How the Rose-Ringed Parakeet Conquered the Western World

https://mforamsterdam.com/the-green-invaders/

“Dad, what are those birds? I’ve never seen them before” I remember asking my dad when I was younger.

I had never seen or heard them before, but suddenly there they... Continue Reading →

Gulls are taking over our European cities

Coastal cities in Europe are swarmed with gulls, to the annoyance of many of those cities’ inhabitants. Gulls (Larus spp.) are naturally cliff-nesting species, but are able to thrive in urban areas because of the high food availability, the suitable climate, the similarity of nest substrate, lesser risk of predation and the presence of conspecifics...

Navigating towards a quieter urban environment: mitigating the threat of traffic noise

In today’s urban environment, the constant presence of traffic noise is undeniable, infiltrating even the most hidden corners of the woods. Previous studies have shown that this anthropogenic noise negatively affects the welfare of both humans and other species. The fact that even unborn organisms experience negative effects is a worrying development, emphasizing the urgent... Continue Reading →

Focus points for urban biodiversity conservation planning and design for birds, reptiles and amphibians

Urbanization is happening all over the world. Everywhere you look, you can see that cities are expanding and new cities are being built. This is often at the expense of nature. There is not a lot of room for vegetation in cities and more and more existing vegetation and farmlands are being turned into urban... Continue Reading →

Is agriculture actually beneficial for avian biodiversity?

It is a common belief that human-modified areas, such as farmlands, support fewer bird species than natural habitats such as forests. However, new research by Zhao et al. (2024) challenges this idea. Their study of bird species diversity on islands off the coast of China has unexpected results that suggest that farmlands might play a... Continue Reading →

From Twigs to Trash: The Surprising Evolution of Bird Nests

Did you know that it has been estimated that the anthropogenic mass, representing all human-made objects, would exceed the living biomass in 2020 ± 6 years? Each year, humans accumulate 30 Gigatons of anthropogenic mass, based on the averages of the last 5 years. The article that made these estimations even mentions that “this corresponds...

How Gull-ible can we be around urban Larus?

The weather on the northern hemisphere is getting warmer which means beach days are approaching. Every beach dweller can confirm that seagulls (Larus sp.) can be very cunning and cheeky in order to steal food. Is this their ancestral behaviour or has this evolved with the rising of urban areas? Pavlova and Wronski (2020) studied... Continue Reading →

(Sub) Urban Observations: Greylag geese nesting in trees & nest hijack by a leucistic duck?

Knotted willows characterise many Dutch landscapes, where they are often seen in a row along creeks that have existed for decades. These willows are pruned every few years, which causes the characteristic wide “knot” at the treetop to form over time. Complex shapes can form due to this pruning, and it is quite common to...

Student Media Highlight: Life in the City mini-documentary

Our perceptions of wildlife and nature are shaped by the media which highlights. The mold has been set by great figures like David Attenborough, with his memorable narrative voice. However, these documentaries only explored 'pristine' landscapes in far away lands, while ignoring the creatures that must contend with the Urban Jungle. In my first (and... Continue Reading →

Urban Observation: Little Ringed Plovers on Urban Tidal Marshes

Who would ever have expected to see plovers on the banks of the Huangpu River in Shanghai? The Huangpu River is the "mother river" of Shanghai that flows north throughout Shanghai. It passes some of the most population-dense regions of the city, including Lujiazui and the Bund, and provides green paths on both banks for... Continue Reading →

Urban Observations: Northern Cardinal eating a Spotted Lanternfly?

Spotted Lanternflies (Lycorma delicatula) have become an unavoidable nuisance since their arrival in the Big Apple in 2020. These clumsy hemipterans have managed to dominate the urban jungle due to their bright red warning coloration, which is indicative of their bitter tasting chemicals they uptake from their favorite food source, the Tree-of-Heaven (Ailanthus altissima). Despite... Continue Reading →
