I'm going to need bigger gourds- 10 nestlings in one.

Backstory: 5/29 - 2 eggs, 5/31- 4 eggs, 6/3 -- 8 eggs ( 1 too many for only three day interval), 6/6 - 10 eggs total. I guessed at a hatch date of 6/17 on a 6 egg clutch based on the last egg laid on 6/2. On 6/17, 2 nestlings and 8 eggs were noted. 6/19 - 7 nestlings and couple eggs but it was a bit...

Re: What do you do when a fledling falls to the ground?

Don't hesitate to do nest checks next year. Your martins will not abandon your colony. In fact, they will be back within minutes and as you regularly conduct nest checks, they will return even faster. Your comments indicate that you have been somewhat hands off. Many martin landlords are also not ac...

Re: What do you do when a fledling falls to the ground?

What I do is go to my records, check the cavities to see who is short one bird and put it back. However, if you have no records, you can lower the house and place the nestling in a cavity with similarly sized nestlings, being carefully not to place it in a nest with 5 or 6 nestlings. That might over...

Re: Liquid 7 ??

Bill, I used liquid Sevin to mist the inside of the gourds in half of my and dusted the others when I had black fly issues a couple years ago. The liquid dried quicky and was less apt to become airborne than the dusted cavities. That may be an advantage as far as a safety issue with nestlings. As fa...

Re: Questions following today's nest check

There are always variables in clutch sizes. Your ASY hen could be older and on the downhill side of her productive life, or any other numbers of reasons. They're just birds. I have had ASY lay anywhere from 3 to a high of 8 eggs. The 8 eggs clutch hatched 7. Hatching is "defined as the number of day...

Re: All of my birds are gone

My first nests are not scheduled to hatch until June 16th. The last birds will be leaving here around the first week or so of August...

Re: Starlings!!!!

You will not be available all day to discourage the starlings. They will drive you crazy. Assuming that you can remove the round entry gourd and replace it with the same entry that the pair is also using, that would be my suggestion. Place the nest material in the new gourd and let it go.

Re: to nest check or not to nest check - old babies

How old are the oldest nestlings? Premature fledging is more likely with 22 day old and older nestlings. I push it a bit and have had no issues.If you have been regularly doing nest checks, the nestlings will be used to the activity. I do a lot of nest checks / replacements. Do you know the expected...

Re: My birds don’t stay overnight... why?

Watch just before it gets too dark to see well. They will often come in to the cavity at the last minute. It may be that they are trying to not give predators a chance to see where they are nesting or roosting for the night. I was once just about to give up waiting for martins to show up when I firs...

Re: Have you had 100% occupancy?

Interesting question. The answer may depend in part on geographical location. In the Great Lakes and across the upper tier of the martin range, historically lower martin numbers may make 100% occupancy challenging. I was always envious of those in the south who could have large colonies because of m...

Re: Do they need privacy at first?

Wait. Actually, I see no reason to change the gourds with the crescent entries. Half of my large plastic gourds are crescent and the other half are modified excluder entries and all are filled yearly. None have tunnels. Why spend more money on gourds with tunnels? Changing or removing anything at th...

Re: Nestlings from two nests banded here in 2018 find each other

I don't know how rare this is across the martin world. Banding allowed us to document this pairing, so now we are aware of the possibility. Anyone who loves nature, and birds specifically, can increase the odds by actively managing their martin colony to assure that more hatched martins eventually f...

Nestlings from two nests banded here in 2018 find each other

June 28, 2018, 65 nestlings were banded at my colony. Two years later, two now adult martins, after two round trips to South Americia, found each other and formed a pair. Both were banded with federal bands only 7 digits apart and my Wisconsin red bands WI 003 and WI 010. What are the odds? There ar...

Leave everything up. A friend near me began his colony in the later half of June several years ago. Both birds were ASY martins. They could have come from a predator attacked colony or had their colony hit by a storm. Who knows? Keep trying to attract martins. Someone else's misfortune may be your s...

Re: Random HOSP thoughts.

# 4 is best soption. Just cover the existing entry with the 1 3/8 inch hole cut into a thin piece of plastic as you might have from a cottage cheese container or something similar. Staple it over the entry. A very inexpensive conversion.
