[cayugabirds-l] more nestbox woes

2022-05-18 Thread Fredric Kardon
Today I checked all 4 of my nestboxes.  There are two groups of two each.
The two groups are about 350 ft apart.  The group where I saw a male house
sparrow 2 days ago had a male house sparrow sitting on top of it again.
There was the same nest in the box but no eggs.  The other box was empty.
In the other group I saw a tree swallow fly out of the box and a little
while later a tree swallow flew into the box.  I thought that meant this
was an active tree swallow nest and I did not disturb it.  The second box
in this group had a dead tree swallow sitting on a nest.  I removed the
nest with the tree swallow and on the floor of the nestbox were about 20
wriggling insects.

What is going on here?

There are 2 photos of this on my ebird checklist:

Thanks, Fred Kardon

[cayugabirds-l] Possible Golden-winged Warbler at Sapsucker Woods

2022-05-18 Thread Anne Marie Johnson
In the vicinity of the Sherwood Platform on the Wilson Trail in Sapsucker Woods 
this morning I heard what sounded to me like a variation of a Blue-winged 
Warbler song- the typical higher buzz followed by a lower buzz, but the higher 
buzz was repeated, so two initial higher buzzes followed by the typical lower 
buzz. The bird repeated this song several times and move about quite a bit, but 
I never got a look at it aside from a glimpse as it flew from one spot to 
another before it either flew too far to hear or stopped singing. I heard a 
typical Blue-winged song in the same area on Monday. Since the song sounded a 
little different, I recorded it on my phone using the Merlin app, which 
identified it as a Golden-winged.

RE: [cayugabirds-l] bird carcasses for the Cornell Museum of Vertebrates

2022-05-18 Thread b_clise
Late yesterday I discovered a deal female Baltimore Oriole in my yard. Since 
their arrival, I've seen several here, observed nest building in 3 locations, 
and have been going through grape jelly at a feverish pace. I considered 
retrieving the body for donation, but a male has been frequently landing on the 
carcass, looking at it, fluttering it's wings, then flying off, several times 
per hour. I opted to let nature take its course and let the poor little guy go 
through its grieving process ( if that's what's going on?). Also worth noting , 
I have no orioles at my feeder (highly irregular) and only 2 males chasing 
eachother through my yard, versus the presence of several in the trees. I'm not 
sure why these sudden changes but will keep watch. I can only guess some sort 
of predation. Barbara Clise,  in King FerrySent from my Verizon, Samsung Galaxy

 Subject: [cayugabirds-l] bird carcasses for 
the Cornell Museum of Vertebrates Dear Cayugabirds community —When you 
encounter birds in New York State that have died of natural causes and that are 
in good condition, please consider donating them to become specimens in the 
Cornell Museum of Vertebrates, which is located in the same building as the Lab 
of Ornithology. At the CUMV we largely rely on these ’salvage’ specimens to 
keep our collection current, as there are all kinds of things one can do with a 
modern specimen that can’t so easily be done with older specimens.We maintain 
all New York and federal permits for this purpose. We do not maintain state 
permits for most other states, so please do not donate birds from farther 
afield. The major exception pertains to Bald and Golden Eagles: special federal 
laws cover eagles and we are not allowed to accept eagle materials.When 
preparing to bring us a bird carcass:1. Place it in a ziplock-type bag, one 
bird per bag.2. Inside the bag include a slip of paper that notes the date the 
bird was found, the location, and your name. Specimens without date and 
location have little research value.3. Put the bag in your freezer if you must, 
but then bring it to us as soon as possible (technically, you are allowed to 
possess these birds only if you are actively bringing them to a designated 
museum like the CUMV).4. On arrival at the Lab during open visitor hours, just 
let the person at the front reception desk know that you want to drop off a 
specimen.Please be sure to consider your own personal health and safety when 
handling dead birds. If you can use a ziplock like a ‘glove’ and never touch 
the bird, so much the better. If you need to touch it, wash your hands 
immediately and thoroughly. As you probably know, this is an avian flu outbreak 
year, so being especially cautious is wise (though there have been no human 
cases thus far). Personally I would not hesitate to bring in a bird that died 
of a known trauma like a window-strike, cat kill, or car-strike, but I would 
think twice about handling without PPE a dead bird found with no known cause of 
death.Best to all,Irby LovetteDirector, CUMVBegin forwarded message:From:

Lawrence's warbler - mortalityDate: May 16, 2022 at 9:12:34 AM EDTTo: 
CAYUGABIRDS-L Reply-To: Andrew David Miller 
Due to the rarity of this warbler, I thought that 
some might be interested in the following.  I found a window mortality 
Lawrence’s warbler outside of the Veterinary Research Tower on Cornell’s campus 
this morning.  Bird mortalities have decreased here since they put new glass in 
about 6 years ago, but every spring and fall there are still a few dead birds 
that I find. In case anyone wants the bird for study, I have saved it in my lab 
freezer. -Andrew Miller --Cayugabirds-L List Info:Welcome and BasicsRules and
