Panama Live: The Final Results Are In!
November 16, 2020—Posted by Rachael Mady on behalf of Bird Cams Lab
Cam Viewers Collected Data In Real Time And Made Discoveries About The Foraging Patterns of Tropical Feeder Birds
For the first time ever, viewers from around the world collaborated with scientists to collect data in real time while watching the Panama Fruit Feeder cam in an investigation called Panama Live. From February 10 – 24, more than 60 people around the world made over 11,000 observations to answer the community-chosen research questions: “When do focal species arrive at the feeder, and how does this vary from day to day? Does the timing of food affect when birds arrive at the feeder?”
They sought to better understand the foraging patterns of six tropical species that we know little about: Clay-colored Thrush, Crimson-backed Tanager, Gray-cowled Wood-Rail, Gray-headed Chachalaca, Rufous Motmot, and Thick-billed Euphonia.

Once the data was collected, the Bird Cams Lab community came together to explore the data via interactive graphs, online forums, and a live webinar in which we watched highlight clips of the focal species and discussed patterns in the data. Today we conclude the Panama Live investigation with the final step: sharing out the results.
Looking at the data, it appears that the six species greatly differ in their arrival patterns, within and between days. Some species, like the Clay-colored Thrush, have a high percentage chance of arriving at the feeder throughout most of the day (Figure 1) while other species are more likely to visit in the morning and evening, showing a bimodal pattern (Figure 2).
Clay-colored Thrushes Were At The Feeder All Day
Two Species Were More Likely To Visit The Feeder In The Morning Or Evening
One of the most intriguing patterns in the data, and one that several Bird Cams Lab members proposed several ideas to explain it, was the delay in the arrival of the Gray-cowled Wood-Rail once food was put out (Figure 3).

In the live webinar, many people echoed each other’s ideas or offered additional ones to explain the pattern:
Does the rail show up some time interval after some other species, as though they use the other as an indicator that there’s food? —James Roper
Maybe the rail doesn’t keep an eye on the feeder to see when the food is put out but notices increased activity and goes then, or even waits until the increased activity dies down a bit. —Mary Ann Good
Do the wood rails come at times to avoid other birds, such as the chachalacas? —David Hamilton
Additionally, Bird Cams Lab members asked to know more about how “sampling effort” varied throughout the data collection period, so we made an extra set of visualizations. By sampling effort, we are referring to the amount of time at least one participant was watching and collecting data on the cam. This data isn’t biological, but methodological, and is important to consider when interpreting the biological data.
We now bring the first-ever co-created investigation on the Panama Fruit Feeder cam to a close. Thank you to everyone who participated in Panama Live, whether you helped us come up with the questions, collected data, explored the data with us, or reviewed the final report, your input shaped this investigation. Thanks to this team effort, we know more about the foraging patterns of six species that visit the Panama Fruit Feeder cam. Our preliminary findings can help inform future investigations with this cam and others!
