I was browsing through my photo archives last week and came across an unprocessed RAW image of an American Avocet and its reflection. I thought it had potential so I went ahead and worked on it.
I made this in Merritt Island National Wildlife Refuge on March 3, 2015. It got me thinking – I know, proceed with caution, right?
The last time I was over there, I spent a few minutes talking to someone and he mentioned that there are fewer birds there now than there used to be. I hear comments like that a lot when when I’m out photographing. I couldn’t recall the last time I’d seen an Avocet but I knew it’d been a while. Maybe there are fewer of them around. When I went back into my archives in Lightroom, it turned out my most recent photo of one is from January of 2021.
I don’t see too many of them, and they’re distinctive enough that I’m sure I’d notice them if they were there. But my data is sparse and can’t really say if these birds are getting less frequent around here. So how can I tell?
I’ve mentioned eBird.org before. It’s managed by the Cornell Lab of Ornithology and collects data on bird sightings from all over the world to “document distribution, abundance, habitat use, and trends”. Maybe if we look there we can see if there are fewer Avocets now at MINWR.
There’s a tremendous amount of data and science resources on eBird. But I couldn’t find specific information on year to year trends. So I looked at the specific page for MINWR bird observations: https://ebird.org/barchart?byr=1900&eyr=2022&bmo=1&emo=12&r=L123565. If you search for American Avocet on that page and click on the little graph symbol next to the name, it opens this page: https://ebird.org/barchart?r=L123565&bmo=1&emo=12&byr=1900&eyr=2022&spp=ameavo
Then you can select different metrics and date ranges. I chose to look at the “Totals” tab, which is the “sum total of all counts from all observations for a species within a specified date range and region”. I picked two date ranges: 2007 – 2014, and 2015 – 2022 to compare and see if I could tell if there are fewer avocets now than when I first started going over to MINWR.
This seems to say there are about twice as many American Avocets seen at MINWR recently than there used to be. But… it isn’t normalized to account for the increased reporting by more birders as time goes on. So I don’t think these numbers are an accurate representation of the number of Avocets actually there. Is there a way to determine the accurate numbers? Sorry – I couldn’t find one. But I’ll keep looking and let you know.
Thanks for stopping by and reading my blog. Your visits, comments, and likes are always very welcome and a big motivator for me. Stay positive, be kind, take care of yourselves and each other. And if you can, make some bird photos now – in case their are fewer opportunities in the future.
