Fig. 1 from the article: Three potential processes resulting in two species with different nonbreeding strategies: (A) nonbreeding adaptive divergence arises after complete reproductive isolation. (B) Diverging lineages evolve nonbreeding divergence during a period of allopatry. Scenario (C) is a proposed model of sympatric speciation via the evolution of novel nonbreeding strategies. Alternatively, in scenario (D), divergence in nonbreeding strategies arises but does not precipitate reproductive isolation.
Award issue: @pjdougherty.bsky.social and Matthew Carling review where and when nonbreeding divergence may influence reproductive isolation and speciation

Day 24 - Molt from @mkohomemadedesigns.bsky.social !
From old to new, here's a lil bug!

Don’t catch a cold dear brave lady blackbird. Your insulation isn’t all that at the moment. It’s been pouring all day with just a few spells of sunshine. 🪶 #blackbird #merel #moult #windowwildlife
This female blackbird really takes the brunt of the moult. In six weeks she will be shiny and new, now she’s vulnerable. 🪶 #blackbird #merel #moult
Some hardly have time to recover from raising the kids before moulting. They must be exhausted. 🪶 #greattit #koolmees #moult #windowwildlife
Moult makes them vulnerable and it also affects their flying ability. That’s why I feed them in summer as well, seeds, mealworms, insect suet balls, peanuts, whatever they need to get through it. 🪶 #greattit #koolmees #moult
Some adult birds go straight into moult after raising their brood. It takes a lot of energy and it makes them very vulnerable. Ticks can make them lethargic. 🪶 #hawfinch #greattit #moult #appelvink #koolmees #wildlifeNL #nature
The Riverfly HQ team found the shed skin from the final moult of a Mayfly during their June sample! 💙
A reminder of the Mayfly's fascinating lifecycle ✨

I will be including this in my app in a future update.

Fig. 1 from the article: White-chinned petrels moulting 4–5 inner primaries at the start of primary moult also replace most of their greater secondary coverts before the start of secondary moult (photos by Peter Ryan).
Fig. 4 from the article: Temporal distribution of the proportion of primary feather mass grown (PFMG) of adult white-chinned petrels accidentally caught by fishing vessels off southern Africa. The continuous line shows the average moult trajectory, dashed lines show 95% confidence intervals.
NEW PAPER: exploring variation in wing and tail moult in >2400 white-chinned petrels. Large sample size reveals considerable variation among individuals, which is surprising given the high cost of moult.

Hello water friends #seals #seapuppies #horseygap #norfolk #moult
So Ara has finally moulted and for the first time ever I've got a clean enough moult to sex for sure......I knew it all along she's my girl not my boy.... (Inside abdomen of moult) #tarantulas #salmonpinkbirdeater #moult #exoticpets #invert #inverts #invertebrates #petdad

My first PhD paper looked at 🪶feather growth rate in 4 different #StormPetrel species! We were the first to compare species breeding on opposite hemispheres, and our results suggest different energetic demands during #moult between the north and south. @peerj.bsky.social doi.org/10.7717/peer...
