[cayugabirds-l] Snow Goose estimate methodology.

2021-03-18 Thread metetlow 
Here is my ebird checklist from yesterday to give people an idea how I came up 
with 400k:
Lower Lake Rd., S of Cayuga Lake SP
Mar 17, 2021
1:42 PM
Traveling
1.60 miles
130 Minutes
All birds reported? No
Comments: Submitted from eBird for iOS, version 2.4.1 Build 2.4.35

40 Snow Goose -- Estimated two ways. First, I used my odometer to determine 
the length of the flock along the road as 1.6 miles. Then I randomly counted 
one row of geese straight out which averaged 100.  Figuring one row every 2 
feet comes out to 422,400.  Second, I used Google Earth to draw a closed area 
on the map that the flock occupied. This came out to 444,519 square meters. 
Using one bird per square meter to arrive at 444,519. Those densities may be 
high so I rounded down to 400,000. That being said there was another quite 
large raft in the middle of the lake that I did not work on.

Number of Taxa: 1

[cayugabirds-l] Nesting Mourning Dove

2021-03-18 Thread Johnson, Alyssa 
The past few mornings of walking my dog, I have noticed a Mourning Dove on an 
old Robin nest on the side of a house. The mate is nearby, keeping a watchful 
eye. I got fairly close to the nest on the house before realizing the bird was 
on the nest, but she didn't budge.

Is this early for nesting? Seems so!
