In this episode, we have an exciting mix of cute pictures and interesting stories, including an update on the romantic lives of falcons.
Peregrine Falcons have made an amazing recovery in Illinois over the past few decades, thanks to the hard work of Field Museum staff and volunteers. Researchers have been studying how these birds are adapting from living on cliffs to nesting on tall buildings in cities.
In the wild, Peregrine Falcons usually stay with the same partner for life. Scientists wanted to know if living in cities would change this behavior. Their research shows that falcons in Chicago are just as loyal to their partners as those living in rural areas.
The research team, including Field curator John Bates, collections staffer Mary Hennen, and UIC graduate Isabel Caballero, used field observations and DNA testing. They took blood samples from baby falcons to compare their DNA with their parents. Out of 35 chicks tested, only one showed signs of having a different father. However, this might be because the male falcon lost his partner and found a new one.
Learning about the breeding habits of these falcons helps us understand how they adjust to city life and how urbanization affects different species.
Next, let’s explore mouse lemurs, the smallest primates in the world, and their role in understanding Madagascar’s unique environment. Madagascar’s isolation has led to the development of many species that exist nowhere else on Earth.
Recent research by Field Museum associate Anne Yoder and field biologist Steve Goodman has provided insights into the evolution of mouse lemurs. These tiny creatures reproduce quickly, reaching adulthood within a year, which allows them to change significantly over generations.
The study found that changes in habitats that separated mouse lemur populations happened about 50,000 years ago, long before humans arrived on the island. This suggests that natural climate changes, not human activity, were key in shaping Madagascar’s geography.
Finally, let’s dive into the origins of our Solar System. Recent studies by star-stuff and nanodiamond curator Philipp Heck and post-doctoral student Levke Kööp focus on meteorites, especially carbonaceous chondrites, which are rare and make up only 4.6% of all meteorites that fall to Earth.
These meteorites contain calcium-aluminium-rich inclusions (CAIs), which are important for understanding the early materials that formed our Solar System. By studying these CAIs, scientists can learn about the types of stars and events that contributed to our cosmic beginnings, suggesting that our Solar System might have formed from a rare type of supernova.

Imagine you are a Peregrine Falcon living in a city. Create a short skit with a partner about your life, focusing on how you adapt to urban environments while maintaining loyalty to your mate. Consider the challenges and benefits of city life for falcons.
Become a DNA detective! Use a simple online tool or a classroom activity to simulate how scientists compare DNA samples. Analyze fictional DNA sequences to determine parentage, just like researchers did with the falcon chicks.
Create a timeline that illustrates the evolutionary changes in mouse lemurs over the past 50,000 years. Use drawings or digital tools to show how natural climate changes influenced their development and the unique biodiversity of Madagascar.
Research different types of meteorites and their significance. Present your findings to the class, focusing on carbonaceous chondrites and their role in understanding our Solar System’s origins. Include visuals or models to enhance your presentation.
Start a journal to observe and document wildlife in your local urban area. Note any adaptations you see in animals living in the city. Compare your observations with the behaviors of Peregrine Falcons in urban settings as discussed in the article.

**Peregrine Falcons: A Study on Fidelity**
Peregrine Falcons have made a remarkable comeback in Illinois over the last few decades, thanks to the diligent monitoring efforts by Field staff and volunteers. Ongoing research has focused on how these birds are adapting from their natural cliff-dwelling environments to urban high-rise buildings.
While we know that these birds typically mate for life in the wild, researchers were curious about whether urban living would lead to increased interactions with neighboring breeding pairs. Their findings indicate that breeding pairs in Chicago remain faithful to one another, just like their rural counterparts.
The research team, including Field curator John Bates, collections staffer Mary Hennen, and UIC graduate Isabel Caballero, conducted a combination of field observations and DNA testing. They analyzed blood samples from baby chicks to compare their DNA with that of their parents. Out of 35 offspring tested, only one showed evidence of infidelity. However, it’s also possible that the male had lost his mate and paired with a new female.
Understanding the reproductive behaviors of these falcons enhances our knowledge of how they transition from rural to urban environments and the impact of urbanization on different species.
**Mouse Lemurs: Nature’s Time Machines**
Now, let’s talk about mouse lemurs, the world’s smallest primates, and their fascinating role in understanding Madagascar’s unique geography. Madagascar’s isolation has allowed for incredible species diversification, resulting in organisms found nowhere else on Earth.
Recent research co-authored by Field Museum research associate Anne Yoder and field biologist Steve Goodman has shed light on the evolution of mouse lemurs. These creatures breed rapidly, reaching reproductive maturity within a year, which allows for significant changes over generations.
The study found that habitat changes that isolated mouse lemur populations occurred around 50,000 years ago, long before humans arrived on the island. This indicates that natural climate changes, rather than human activity, played a significant role in shaping Madagascar’s geography.
**Star-Stuff and Nanodiamonds: Our Cosmic Origins**
To wrap up this episode, we delve into the origins of our Solar System. Recent publications by star-stuff and nanodiamond curator Philipp Heck and post-doctoral student Levke Kööp explore the formation of meteorites, particularly carbonaceous chondrites, which make up only 4.6% of all meteorites that fall to Earth.
These meteorites contain calcium-aluminium-rich inclusions (CAIs), which are crucial for understanding the early materials that formed our Solar System. By studying these CAIs, researchers can gain insights into the types of stars and events that contributed to our cosmic origins, suggesting that our Solar System may have formed from a rare type of supernova event.
