The second field season of #TrophiChange was completed a few weeks ago. Here's a thread of what I was doing.
#ornithology #SciComm #waders #shorebirds #fieldwork
I am interested in linking #whimbrel chick growth to their food resources. To do that, I started in May by finding as many nests as possible. More nests = more chicks. This season that meant 110 nests.
#ornithology #TrophiChange #waders #shorebirds #fieldwork
But nests of several other species were found and surveyed too, to record laying dates and hatching success, as part of our centre's long term monitoring of breeding #waders in #Iceland.
Here's a golden plover nest, that successfully hatched. #TrophiChange #fieldwork

Here is a list of 45 #birds, 22 #mammals, and 30 non-avian #reptiles that are CRITICALLY ENDANGERED due to feral or pet #cats
#invasivespecies #conservation #ornithology #BiodiversityCrisis
pnas.org/doi/pdf/10.107… Image
first off, I'd like to highlight that "feral #cats on islands are responsible for at least 14% global #bird, #mammal, and reptile extinctions and are the principal threat to almost 8% of critically endangered birds, mammals, and reptiles"
onlinelibrary.wiley.com/doi/epdf/10.11…
AND within our own lifetimes, North America has lost more than one in four of its birds. These are not all critically endangered now, but these trends are pointing to #extinction

The Rock Dove is the original form of the feral/domestic pigeon – among the world's commonest birds. But did you know that Rock Doves might go extinct 🧬?

🚨Here is my (first!) paper @iScience_CP!🧵

The pigeons in towns all over the world are ‘feral’ 🏢🐦. This means they are ‘free-living populations of domestic origin’ – (sort of) like British moorland ponies 🐴🇬🇧 or Australian dingoes 🇦🇺🐕. Feral pigeons are cool animals (@EJTatham @E_Carlen!).

The wild forms of many feral animals are rare. Scotland’s wildcat 🏴󠁧󠁢󠁳󠁣󠁴󠁿🐯 has hybridised with domestic cats 🏠🐱. The Red Junglefowl 🌴🐔 is threatened by the chicken! We wrote about this last year: doi.org/10.1111/cobi.1…

Thank you and welcome – a wonderful honour to give this #BOU2022 #AlfredNewtonLecture talk. A sight for a curious naturalist: why is this warbler apparently so silly? Or, how does the cuckoo get away with this?

#ornithology
2 #BOU2022

The talk celebrates Alfred Newton, founder of the BOU in 1858, the year of Darwin and Wallace’s papers proposing the theory of natural selection. Newton was an immediate early fan.

#ornithology
3 #BOU2022

Newton’s paper in 1869 suggested that egg-colour variation in different host-races of Common Cuckoos was a result of natural selection. He coined the term “gentes” (singular “gens”) for these host-races

Welcome to #BOU2022, Avian Reproduction, the BOU’s 2022 annual conference .

Our three-day conference is on Zoom and on Twitter and is a genuinely low carbon even.
By making #BOU2022 virtual we've also taken it global and have expanded the event way beyond the UK-dominated attendance of an in-person conference with this Zoom conference having nearly 2x the delegates, 36% of whom are from outside the UK.
And not only are all the #BOU2022 Zoom presentations summarised here on Twitter, but you will also enjoy some Twitter-only presentations that aren't being presented on Zoom during the breaks of the Zoom conference.

Our paper (with @LeaGrie) on the functions of #bird #odour is out in Biological Reviews doi.org/10.1111/brv.12…

Don’t have time to read the full paper just yet? Here’s a summary thread 🧵 [1/14]

#olfactory #camouflage #communication #ornithology #avian #olfaction #crypsis
Preen oil is produced by the uropygial gland and birds use it to maintain and waterproof their plumage. But could it have other functions? 🤔 [2/14]
Over the past 20 years, researchers have explored whether preen oil plays a role in chemical defence & communication. Despite this growth in research, many functions of preen oil remain poorly understood 🧐 [3/14]

¹Hello! Your friendly birder here introducing you to another cool grp of birds
MOUSEBIRDS!
¹Red-faced Mousebird
²Speckled Mousebird
This is 2 of the 3 in southern Africa
Like their name, they have cool similarities with mice. They hang out in grps clamoring on trees like mice..
²they are grey with long tails, a crest and short legs adapted for tree crawling. If you watch them on trees, get do look like mice🐀
There are 6 spp of Mousebird & all are confined to Africa. They are evolutionary distinct & special (someone can add here)
³they eat a wide variety but mostly fruit. They like to huddle together to keep warm. From time to time, you can see them on tree tops seemingly basking in the sun.
Cool fact: they bask in the sun with their bellies facing out to help with digestion...fermantative digestion 😉

New paper warns of catastrophic loss of EU's birds. Net loss of 600 million birds between 1980 to 2017

That's one out of every six birds

#ornithology 1/12
In fact, 900 million birds have been lost during that period, but this is set against an increase of around 340 million in some species

The eight species showing the largest declines make-up around two thirds of this total decline & the same is true for increasing species

2/12
The house sparrow has been worst hit, losing 50% of its population - 247 million birds.

Changes in agricultural policy and management have driven declines, however urban populations are also declining which may be linked to food shortage, avian malaria or air pollution

1. #BOUasm21 #BREAK1 Light pollution is devastating for #seabirds 💡It causes disorientation, fallout and deck strike/collisions. Our team @NNZST @ScienceUoA investigated if certain types of lights were more attractive to seabirds from their visual perspective!👁️🐦 #ornithology
2. #BOUasm21 #BREAK1 New Zealand is a #seabird hotspot with >25% of global seabird species. 26 species (mainly Procellariformes) breed in the Hauraki Gulf. Our team researched seabird light attraction at 3 islands and 1 peninsula in the Hauraki Gulf💡🐦#ornithology #conservation
3. #BOUasm21 #BREAK1 We used 6 types of boat lights, measured the irradiance, shone them randomly into the night sky, and counted the number of #seabirds visiting the light💡Each light was shone individually for 10 minutes followed by a dark control period for seabirds to adjust

For the return of the #UNMBioblog after our year hiatus, I chose to write about the negative consequences for cats, humans, and #wildlife when we allow #cats to roam freely. I couldn't help myself with the punny title.
unm-bioblog.blogspot.com/2021/09/catast…
I was inspired to write this blog after I witnessed my neighbor's outdoor pet #cat killed a #bird under my feeder. A heated argument ensued. I know nothing has changed because I still scare him out of my backyard. I've counted 9 different cats in my backyard, here is one
I am a paradoxical #catlover, which stems from my #science & #ornithology career. I know how cute it is for my own #cat to frolic in flowers but I understand how dangerous it is for #cats, human #health, & #wildlife when cats roam #CatsOfTwitter #Caturday #catsofinstagram

Spring Waders 1/12
@BirdTrack tells us that the first Little Ringed Plovers are arriving back in the UK. They are not the only #waders on the move, as you can read here:

I'll pull out some highlights in this thread. Image
Spring #waders 2/12
Stone-curlews are arriving too, most having spent the winter in Spain, Portugal, Morocco or Algeria. You can find them on their territories during the day but they will feed elsewhere at night. More here:

Greenshank are on the move. Scottish-breeders have already left English estuaries. Their feeding spots will soon be used by birds that have wintered further south and are heading for Scandinavia:

Back from Mayfield Park, a mix of wooded, beech-dominated hillsides and seasonally flooded, willow-dominated valley. Here's a thread of things I saw. First of all, active burrow complex. Either badger sett or fox earth, I think badger... ImageImage
The UK needs more thickets, they're really important for small birds, mammals and arthropods, especially in the winter. There are a few good ones in the park, I hope that they persist... ImageImageImage
Robins are abundant, and tame and ready to approach people. I've written about #robins at #TetZoo, here's an article.... web.archive.org/web/2015073017… #passerines #birds #ornithology Image

1.#tropicon Estimating bird diversity in tropical forests is hard. We looked at whether using lots of short surveys (high temporal resolution -HR) is more effective than several long surveys when conducting point-count surveys with autonomous recorders and manual analysis.
2. #tropicon We compared bird species detected by @NargilaMoura analysing 240 x 15 second audio clips (HR) against 4 x 15 minute samples (low res - LR) from 29 Amazonian @RAS_network rainforest sites – both totalling 1 hr of data. Illustrative model below: Image
3.#tropicon We found that HR sampling results in many more species being detected – approximately 50% more species at each site (HR= 66.27±3.77 (SE), LR= 43.37±3.77) and 10% higher gamma diversity! Species were also detected faster using HR sampling. #ornithology #ecoacoustics Image

European Stonechat is a gorgeous bird & an exception among decreasing #FarmlandBirds in Belgium: population increased 4-fold since 2000. Why is #stonechat so successful in man-made landscape?
Paper from RGailly out in #Oecologia @SpringerNature thread #ornithology 📸FCarion 1/10
In our study area, stonechats can choose b/w 3 habitats: clear-cut, grassland & Christmas-tree plantations (CTP) a non-food perennial crop. A previous study shown this crop is offering a higher bird diversity than grassland when hedgerows are scarce. 2/10 sciencedirect.com/science/articl…
But is this a good idea for stonechat to breed in intensive Christmas-tree crop? We compared fitness-related parameters between these 3 anthropogenic habitats. First, ♂️♂️ prefer clear-cut over the 2 other habitats as they are reoccupied earlier after spring migration 3/10
