Here's another one if you're still looking at options (from a definite superfan 🤩)!

The five sides of the exclosure were held together by zip ties, enabling easy disassembly for storage over the winter. [3/4]

Exclosures allowed parents to easy enter and exit nests, but prevented nest predation by crows, ravens, and gulls. This led to many handfuls of nestlings! [2/4]

Research was conducted at the Bowdoin Scientific Station on Kent Island, NB. A huge thanks to coauthors: @ryannorrissci.bsky.social, Linda Nong, @sdobney.bsky.social, @passarahformes.bsky.social, Nikole Freeman, Steph Doucet, @dmennill.bsky.social, and Amy Newman. [7/7]

Our results provide the first evidence for a relationship between baseline corticosterone concentrations and double-brooding in free-living passerines and demonstrate the importance of considering breeding stage when assessing female corticosterone concentrations. [6/7]

We also found that the probability of attempting to double-brood was negatively related to baseline corticosterone in females sampled during the first brood nestling stage, but not in females sampled during the first brood incubation stage. [5/7]

Using 12 years of data, we found that female baseline corticosterone levels negatively correlated with body condition and fat score, suggesting that low baseline corticosterone reflected high female quality in this population. [4/7]

We explored the Quality Hypothesis, which proposes that high quality females have sufficient energetic resources available to rear two broods a season. [3/7]

Double-brooding can substantially increase the number of offspring produced per season in songbirds. However, not all females in multi-brooded populations rear two broods per season. We were interested in exploring this variation in a population of wild Savannah sparrows. [2/7]
